if only riot had kept him as his original monster design XD he could conjure a 10 second time vortex that stunned for 1 second every 2.5 upon entering it
I do agree that it is mega fun to play zilean though...the only sad part is that most people don't engage when they have a poke support and only engage when they have someone like a blitzcrank or etc for easy kills early game
if you want another "make life for the opponent living etc" support, try out support Karthus. high ranged near instant poke damage, a powerful slow that increases his damage even more, his E prevents most diving and if they do dive and manage to kill you, your carry will very likely get a double kill in return, oh, and perfect timing with his ult is just the funniest thing to ensure that double for the carry XD
I wish there were more champions capable of healing...playing soraka or sona as the only true supports kinda gets mega boring, the others are more utility than support, like blitzcrank...near unkillable with "I bring the kills for you" damage...he wasn't designed as a support, he was designed as a solo laner, but if he even tries it, he gets smashed
thresh is the same stereotype only less likely to steal the kill himself and can provide a free 1000 distance blink/dash
tahn kench is nearly unkillable (though haven't played as, just against) and has high poke damage
all of the support roles have fairly died out in riot's designs, like Bard, he's fairy balanced, but annoying to play as and against because his mechanics are almost random
