Evasive strike is not a problematic attack at all. Because to keep evasion they need to use basic attack. Is gallimimus or ornithomimis good,no they are trash. The problem with evasive stance is the dino that used evasive stance can distract, nullify break shields while evasive
Their stats are bad. That is why they suck.
There would be lots of people out there who would outspeed their opponents and just spam evasive strike. Most prepared people have 2-3 nullifiers in their team and if they don’t get any in match some luckiest people would get lots of easy 3-0 wins. Do you really want that?
I actually don’t think this is a bad concept, esp if the damage is kept on the lower end of what would be feasible. Yeah, Evasive Strike may be abused and spammed, but that would also negate a lot of its potential. Plus it being easily nullified by other creatures, and for it to do basically anything else, its going to have to take the hit to get there. Though I might change one move, personal opinion, Nullifying Rampage to Nullifying Impact.
