Over the last couple of months supports have regained some of what they lost in itemization. We got cheap sight stone and crystalline flask when S3 began. This was found OP, and prices where increased accordingly. Fiendish Codex had it's mana regen removed, which was also something supports could make use of. Riot still wants us to have some items that are useful alternatives to the aura stacking, and they are also interested in giving some low use items more life.
This means the support playerside has seen some stealth buffs with sustain items and GP/10. Last season Philo stone was very popular but would only build into 1 item, now our "basic needs" item builds into several things:
Mikael's Crucible yields plenty of mana regen, MR and an active that will allow your carry to escape a lot of perils.
Ohmwrecker let you become more aggressive. It gives AP, more health and the ability to put a tower out of the equation.
Shurelia's Reverie gives some health, some sustain, some CDR and the all lovely MSpd buff.
I'm a fan of Ohmwrecker, tho I can't recall I have been using it in a game.
Have any of you guys and gals philo stone and building it into something different than Shurelia's, if so what and why. And was it worth it?
