These people going into arena with blue gears who have barely touched trials and want pets removed are silly to me. Spirit scar pets are basically necessary in a lot of cases to shut down zumi knights. Changing classes is also solid, in my opinion. An illu queues in against a team of 3 orange and they may as well sit there and die, if the illu is good. Let one of them change to knight. Not sure if the health vote is arena-only or if you mean health overall, but if it's overall, that's just silly. Do your trophy achievements and level your classes. 4 yellow certs and/or a 50 MA cert are enough for 99% of cases, with the 1% being Shale T crits from Robo.
Edit: I assume health is strictly arena. In that case, it's still fine as it is. It seems like it's too low in some cases if you're running around in trash gear with low level accessories, no trophy enchants, etc. Those are just growing pains.
