Astrologian could easily be built to support either two healers effectively (w/o being too OP or UP) or to where duo-Astrologian comps are viable (w/o being too OP or UP).
I have to be up in 3 hours or I'd expound. But please put a little more argument rather than "rawr, impossibru to balance! OP!!"
It's doable, I'm sick of these blanket statements. Sure, my above point doesn't contribute anything yet either... but like I said, up in 3 hours. I'll edit this tomorrow with a hard argument with supporting points, whereas you guys aren't even acting like you'll provide some sort of legitimate credence to your arguments.
Make one fine point if you wish in the meantime, create some credibility. Just saying, 'bu-but if they can do both it'll be either too OP or too UP or won't work in certain comps' is not sufficient. I'll see you tomorrow.
