Briefly, Athena at 65% plus an elemental is severely limited. As an example, Athena alone does 200 damage, Athena plus elemental is 400 in version 1.8 and 230 in version 1.9. I had just leveled Panther and saw a huge decrease on yellow titans. The decrease should be about 40%, not sure why you had a larger decrease. Boldtusk and Wu should not be touched. although I did not specifically test them.
I would like a less strict limit. However, compared to what was proposed (nerf Athena alone and Wu), this is infinitely better.
Team building is still identical to before, just doesn’t do as much damage as they lowered the damage scaling at low defense values.
Elemental debuffs still worthwhile, just not nearly as much as before: an extra 1k per tile or whatever though is still a lot more damage than any other special one could bring when we’re talking full stack of buffs and titan debuffs.
