there are also a lot of potentially good t2 masteries for resolve im still waiting on. they started to add onto the cunning tree. they could do it for the other trees aswell.
t1 could get adaptive armor back (10% of the higher resistance stat added to the lower one) as a scaling defensive mastery vs. 2 less damage from auto attacks and river movement speed.
t2 could get 10% damage reduction against crits back, considering how high average crit ratings are mid to lategame.
and strength of the ages needs buffs. IF the mastery just stays as is, id at least reduce the bonus from cannons to 15 health and make regular minions give 1 health, so youre not punished as a hard for missing a single cannon minion. also increase the total health bonus at least by 100 to compensate for the loss on veteran scars.
but personally id have strength of the ages just give 10% max health as a bonus to really make it an all out defensive mastery for health stackers.
