Team Comp Thoughts
Everyone has those games where the game feels lost or won at champ select because of Comp. What are your thoughts on good team comps?
Good Team Comp:
Good team comps tend to have a "Triple Damage Line." By this I mean that they have THREE or more of the following: Mage, High Damage ADC, Tanky Juggernaut from Top, Damage Support
Good team comps have 2 dedicated champs who will build full tank or near full tank and whose kits synergies with such build (these champs can be part of the Triple Damage Line but sometimes are not).
Good team comps have at least 2 reliable sources of HARD cc.
Clear Examples:

(triple damage line: Jax, Viktor, Jinx) (Tanks: Jax, Rammus, potentially Blitz)(reliable hard cc: Rammus, Blitz)
(triple damage line: Vlad, Lux, MF) (Tanks: Amumu, Nautilus) (reliable cc: Amumu, Nautilus, Lux sort of)
Notice how its much easier to have a Good Team Comp if you don't go assassin mid. Its not that you can't pick an assassin mid, but if you do, you should create a Triple Damage Line with the other roles and that warps your team comp (ex Vlad top, Kog ADC, Brand support). Its hard to win without AOE.
Also, just to be clear, not all ADCs are necessarily "High Damage" ADCs. I'm not 100% set on this yet.
Common Bad Team Comps:
The following are things that I notice about Bad Team Comps (or comps that make it a LOT harder to win if not impossible in some cases).
The most common problem is NOT having a Triple Damage Line (not having it usually means in late game, you don't have the scaled AOE and reliable damage to win battles as 5 against better comps).
Sometimes there is lack of hard and reliable CC though there is usually some. A lack of tanks is common in low elo.
You should NEVER have more than 1 glass cannon diver/assassin in a team comp. Just NEVER. Its a No No. Your late game will be AWFUL. If your going to have Kha, Zed or Xin on the team, pick one and one only, pick more than one at your peril (better be smurfing). Another way to think about it is this: if you have 2 glass cannon divers/assassins, you probably can't create a Triple Damage Line in your team comp anymore without having the requisite tank frontline; you only have 5 people. Either your AOE will suck, or you will lack front line.
Its very easy to show OBVIOUS examples of bad team comp. So I'm just going to show some NOT SO obvious bad team comps imo.
Why is this bad? (You don't have enough damage, there is no Triple Damage Line. You've got Jinx and that's it, NOTHING ELSE. Picking Zed, who is an assassin and not a mage, means that you are on a timer here. You've over supplied your team with non-damage peel champs and you've got 2 divers/assassins. You DO have enough CC and a frontline, but there are grave problems. Your team better get ahead and STAY ahead or its GG against a better comp manned by similar skilled players).
(More damage than the above comp but not enough. Late game you've only got Viktor and Ashe dealing the damage. They die? GG. Also, Pantheon is NOT a tanky juggernaut who scales in the same way as Darius, Jax, or Fiora.)

Thoughts on Team Comp?
etc are SUPPOSED to be good at making picks and fighting in skirmishes while sucking a bit more in team fights compared to a traditional Mage, tanky Juggernaut, or Damage ADC.
or
. It might be a game design flaw but as of now...
