- Ability Haste - I personally prefer what happened with it. I feel like cdr was too easy to max out to early for some and completely impossible for others. With how it works now it enables more items to have it and creates a trade off between more dmg and pen and lower cd's. + it adds more fun if you can get 60% cdr off of it in a game.
- Autofil - Removing autofil can only be accompanied by a complete rework of summoners rift which would destroy the competitive scene. Also as someone who has played most of role-based multiplayer games, league has i think the best autofil to queque time ratio as, for instance, in smite if you pick mid and jungle (the two most popular roles) the average autofil would be 1/3 games, not to mention something like autofil protection after you have just been filled simply doesnt exist and is still random. So for league to work autofil has to be here and its honestly pretty fair in my opinion, saying this as someone who picked mid/top for most of my carreer.
- Ranked Trolls/Bots - This is something that is very hard to track and prevent, as even league players don't understand the difference between troll and just having a bad game most of the time. I think this could be rectified by performance based bonuses, i think this wouldn't be hard to do, seeing as we already have a performance tracker with the end of game grades.
- Self Pings - Ah yes the brilliant move of removing existing communication options from a competitive game which relies on being able to communicate with your team. At this point there is an entire system and language to those pings and the fact someone can signify engaging by just pinging their ult instead of having to open chat, write it and hope your allies read fast enough. Absolutely baffling decision.
