I'm pretty active in hunt trains and I'm in favor of higher HP. I think the problem will get a bit better as time goes on, but it's pretty rough to actually get a hit in sometimes. I would also like SS ranks to spawn with a 1-2 minute invuln period. The current system encourages people to sit and wait for others to kill the minions to actually spawn it, because if you go to put in the work to spawn the thing you often won't even get to hit the thing before it's dead. A brief invuln period gives the people that killed the minions time to make it to the SS rank they actually helped spawn.
