people will swear up and down tanks are broken and they do to much damage.

This is probably why people think tanks hit hard. People tend to build glass cannon unless you're a juggernaut or tank, so the lack of resistances and squishy builds might be mucking that up.

The problem is tanks tankiness has been slowly eroded over the years, and their defensive masteries were gutted this season, coupled with the introduction of vast amounts of free damage from keystones-- not to mention more and more items introduced that give free damage, more damage, or like Sheen items, or the Echo items, basically give you a free low cooldown spell. Oh, and CDR and crit are on virtually everything, sometimes both on the same item, so damage has certainly creeped for everyone, and defenses have only gotten weaker.

Here, I'm gonna quote myself from a different thread:

" Tanks have less surviability this season than they have in previous ones. It isn't rare to be focuses down in 2-4 seconds in the late-midgame or actual late game fights-- particularly as support tanks; which did not use to be the case prior to this season.

The influx of damage coupled with repeated nerfs to the stats of tank items have weakened the amount of defenses that can be built.

I mean, you mentioned earlier that tanks were weak in season three, but we went from Runic Bulwark (400 Health, 20 Armor, 30 Magic Resist with "Unique Aura - Legion: Nearby allies gain 10 Armor, 30 Magic Resist and 10 Health Regen per 5.") for the first three seasons, then with nerf after nerf we finally got all the way down to our current Locket of the Iron Solari which, yes, gives an active shield, but only has 400 health, 20 magic resistance, 100% base health regeneration, 10% cooldown reduction, and an aura which simply grants 15 magic resist.

You can look at the patch history for most tank items and you will see the current items we have are shadows of their former selves.

Warmogs used to stack up to 1400 health, and give 62.5hp/5, this season it was changed to be out of combat regen focuses and given cdr like every other fucking thing. Now its stats are 800 health (a full 600 less hp than it was at its inception), 200% base health regeneration, 10% cooldown reduction, with a passive that grants 1.5% maximum health every half-second if damage has not been taken in the last 8 seconds if you have more than 3,000 hp. That regen is great if you win a fight and for shrugging off poke; y'know what it doesn't do? Provide in combat anything. It is not the burst protection that 600 hp times your effective resistances, or even the higher in combat regen of the original 'mogs.

The original Randuin's gave 90 armor, and its active also slowed attack speed by 35%; in season 5 it only had 60 armor, 500 health and had a unique passive granting 10% less damage from critical strikes. Its active doesn't affect attack speed anymore, and it lost the old slow (on attack speed and movement speed, mind you) on being hit entirely.

Frozen heart used to be an AoE attack speed reduction of 25%, on top of giving 25% CDR, 99 armor, and 500 mana. The current form is a 15% slow, 20% CDR, 90 armor, and 400 mana incarnation.

Thornmail in season one returned 30% of incoming auto attack damage as magic damage, now its 15% + 25% of your bouns armor-- at least it still has 100 armor, otherwise the item would be built even less than it already is.

Cinderhulk went from 350 hp, +25% bonus hp, and did 17 - 34 damage based level in PBAOE, to 400 health and only +15% bonus hp, but had its damage changed to 9 - 43 damage based on level but deals double damage to minions. This effectively just increases the early and late game variance in damage to champions but buffs the damage to neutral targets. In the end, it trade a fairly significant amount of health for a bit faster of a clear in the jungle. Sunfire Cape, however didn't lose any stats but went from 50 damage a second (and being stackable) PBAOE to 26 - 43 damage one, based on level, with a smaller 50% bonus to minions.

Deadman's Plate went from 600 health, 55 armor and a 75% slow at maximum momentum, to 500 hp and 50 armor and a 50% slow.

Banshee's Veil went from 450 health, 300 mana, and 57 magic resist, and a spell shield every 30 seconds, in combat or not, to 300 health, 70 magic resist and 100% base health regeneration which sounds okay at first, 150 health for 13 magic resist isn't too bad (in terms of gold, 150 hp is worth 16.67 mr) and then you get 100% base regen for a chunk of mana. The real kicker though, is that now the spellshield only triggers after 40 seconds of not taking any damage from an enemy champion at all. This means it can no longer refresh during sieges, or drawn out pokewars/skirmishes. It also means it can no longer refresh mid fight to block a spell just when you need it during lane or while roaming/taking neutral objectives.

Force of Nature (40 health regeneration, 76 magic resistance, 10% movement speed + 1.5% max hp added to regen when under half health) was removed, and Spirit Visage was reworked to provide 500 health, 55 magic resistance, 200% base health regeneration, 10% cooldown reduction and increase healing/regen on you by 25% to take its place. Offering considerably less regen, in exchange for more health than the value of magic resist is loses. Additional, it trades 10% movement speed for 10% CDR which is somewhat a wash. Tanks lost basically their only movement item, but they can use the CDR-- except now there are a plethora of tank items with CDR making some build inefficient. The passive change is much worse by itself, however, it synergies well with other regen items, such as warmogs, or champions with sustain or heals in their kit. Unfortunately, other than Alistar, Zac and Gragas true tanks don't have any healing or regen abilities (No, Mundo, Garen, Darius, Illaoi, Volibear, etc are not tanks, they are juggernauts, see here:http://boards.na.leagueoflegends.com/en/c/developer-corner/3A5uuBw7-champion-subclass-list) and so Spirit Visage offers a less useful passive to most tanks in many situations. All in all, this might be the only tank item I'd call close to the same in power level as options that previously existed.

Guardian Angel lost 20 armor, and you now revive with only 30% of your health and mana instead of 50%.

Hell, Sterak's Gage has only been out for a season and already its lost 100 health (mostly due to ADCs abusing it)

Not even the fucking boots survive, Mercury Treads used to give 35 magic resist and tenacity, now they grant 25 magic resist, and 30% tenacity. Even the tank starting item, Doran's Shield went from 150 health, 10 armor, 8 health regeneration per 5 seconds to 80 health, 6 health regeneration per 5 seconds, and it blocks 8 damage per auto attack/single target ability.

P.S. you know what else? Tanks got completely shafted with our masteries this season to make it that much worse. We no longer get 4% less damage from AoE, or 10% increased bonus armor & magic resist, or 10% less damage from critical strikes, we also lost 2 damage from champions for each instance and tick of damage (absolutely amazing for DoT spells) on top of 2 less damage for auto attacks (stacking with each other). Rather than the rarely used Veteran's Scars we have now, we used to get 36 hp + 3% increased maximum hp (and it even cost 2 less points to do this). Don't forget Adaptive Armor which gave 4% of your bonus armor as magic resistance if you have more bonus armor than bonus magic resistance or 4% of your bonus magic resistance as armor if you have more bonus magic resistance than bonus armor. Finally, may Legendary Guardian (+3 armor and magic resist per enemy in 700 range; so 15 armor and magic resist free every teamfight) rest in peace with FoN, Bulwark, HoG, etc."

So all that tanks have left is weaker defenses, and more access to damage now-- what do you expect them to do but slightly more damage, and die quicker too.
