A mode where we lose all the limits set by league of legends stats. no cdr, attack speed, run speed, unique item effects, and crit (beyond 100% would be guaranteed crit plus chance to do more. ex 150% would be 200% damage with a 50% to be 300%) limits. yasuo with 6 ie? lux 100% cdr? what are your thoughts (for obvious reasons karthus/soraka are perma banned)
Death by Kayn2 votesURF. What you're describing is URF
All Day Tay Tay1 votesurf is a buff to all players. this is a removal of limits
Kouga1 votesThe closest thing we have had is URF which is I think is as close as you can get. This would cause huge problems.
No CDR Limit - the problem with this actually isn't about damage spells but instead is with CC. No CDR means permanent stuns/supresses. Lissandra can literally keep you (or herself) in stasis pretty much indefinitely. Amumu can hold your team in place forever. Etc.
No attack speed limit - would be funny to see but I think it'd cause more technical glitches and bugs than anything, just trying to keep up with the animation and registering hits as you start getting 4.0, 5.0 Attacks Per Second.
Run speed.... technically isn't a limit on run speed but there is a soft cap where you start getting a diminished effect on MS after a certain speed. So removing this would let Rammus move EVEN FASTER! but overall wouldn't necessarily change much.
Unique Items being stackable... lol. 
x6, deals 48% of your current health on hit. 
STACKING BOOTS! 
Can't kill me (assuming they don't all proc at once, but take turns) or Tenacity, you are now immune to CC (Hmmm......)
The crit issue isn't a big deal, except for Yasuo. The items with high crit chance like PD don't grant high damage and the damage items don't grant much crit. Even with 6 IE's, you only get 120% crit chance. This would only be a real benefit for Yasuo.
All Day Tay Tay1 votescc went over my head. your right on that. maybe a timer on cc like how nasus passive works? cant use the same cc on someone too fast? i know run speed is only soft caps but still remove it. honestly i would say GA take turns, but increase the speed of revival, so you cant just stay forever since revive takes roughly 5 seconds so 6 of them means you cant die for a minimum of 30 seconds, on top of the 300 armor/mr you would have, so it would take a while to get that hp you have down as well. attack speed was a thing i had to think of if it was even possible but really if you think about it there is probably a cap to how high it could get. Best attack speed item is runaans, which would be extremely fun to stack the passive as well. so 6x70 is 420 (no i wont say it) bonus attack speed. honestly i dont know enough of the numbers to say who would have the highest attack speed (although im sure its trist with her q). while the attack speed would be extremely high, it would have no damage, so only people with on hit effects would work (tf come to mind, with the bolts he could proc his e like 5 times per attack).

D2Vincent1 votesHow about where the item's UNIQUE Passives are can now Stack with each other....and even benefit from duplicate items!
6 Deathcaps + Karthus = WIN
The Troll King1 votesGlobal Ults would be God Tier because the can just sit at base (Soraka or Fountain Heal still counters Karthus) Kayle, Trynd, and Morg would be the best lane pushers, unaffected by Karthus ult........God tier.
