Soooo many problems with the pre-season
- Yasuo being more broken than ever. He will never be balanced due to the nature of his kit. he needs a complete rework, but for now an ult that only triggers on his knockup could help.
- Tryndamere getting a healing mastery that is equal to or better than his AP tryn healing back in the day.
- Anti-ADC tanks having no counters.
- Few AP champs (brand, anivia, velk) are able to utilize the mastery tree much better than most of the other ones. I am OK with this one, as they are the champs that require more skill than burst-mages, but the benefits can be toned down a little..
- Graves outclassing the other adcs
- Quinn's rework kinda boosted her strengths but didnt address any of her weaknesses
- Guinsoos is either too strong or too cheap.
tl;dr: Yas, Tryn, Tahm, and Mundo need to be nerfed. most other problems can be solved with general tweaks.
