Keystone masteries ruined diversity
Better title: "new mastery pages are less diverse than old ones"
I see myself picking the same stuff over and over again. I don't make any meaningfull choices. Even worse, i am forced to pick useless masteries on a lot of champs because I only have 2 choices so i pick the least bad one.
- I pick almost the same on every APC, Tank, Support, ADC
- Too many times I am forced to pick things I don't want
- I used to pick some flat damage and cdr, defence and utility for supports depening on the situation. Now I am forced to pick tank or scaling AP/AD or even worse %scaling so there is not really a choice anymore.
- Minor differences in masterie pages between toplaner tank, jungler and support.
- Unless you are a healer you pick different masteries than your counterpart.
- The only things that really makes impact are the lv6 keystones. Rest is just crap compared to old mastery tree.
- I don't make any meaningfull choices as support. There is nothing in which i differentiate myself
- Non-tank junglers lack decent masteries which to choose from
Things we lost
- 15% increased range on trinket. I used that one a lot for early cheese during invade
- easy access to mana or mana regen (meditation)
- easy access to 5% cdr
- Generaly speaking APC's lost damage no matter how you look at it
- The chance to pick AD and AP masteries and Armor/Magic penetration. Now we have to choose between both
- flat AD and AP. Also usefull for junglers, supports, tanks for better lanephase.
- flat resistances
- 10% crit reduction
- 3% AoE spelldamage reduction
- Feast for that little extra sustain in lane
- 20 flat ms
- extra damage to monsters
- BUT MOST OF ALL: The ability to shop between every masterie tree for useful and diverse pages for each of your champs. I rather pick a lot of small but useful and impacting masteries than picking useless things just to build up to lv6 keystone. The game has become 'which champs synergize best with the strongest keystones'
... basically anyone who can't proc Windspeaker and isn't a tank.
