I played a game against Trundle support and he's not bad. His pillar blocked my Zenith Blade which was annoying but the high CD means he can't use it all the time.
Yea. Once he gets a CDR item or two though it gets pretty low at max rank (8 ish? seconds). And most of his core build has CDR items on it so it gets obnoxious.
Problem is his laning phase is pretty bad against anyone with solid poke. Sona/Zyra/Nami/Lulu/Karma will dump all over him for example unless they get camped by your jungler, even the unorthodox mage supports like Anivia and Ziggs gave me trouble (though we still won a lot of those). Also Lucian and Ez and Vayne can effectively use their mobility to make it far less threatening
He is pretty threatening against most tank supports though, and will heal off harrass of psuedo pokers like Janna and Soraka pretty handily. he also is pretty monstrous if you take a quick trip mid and put a pillar behind em, they usually have to blow Flash running if their mobility isn't good. He also shreds tanks that like to snowball like Darius/Garen/Udyr and messes up pubstomp channelers like MF and Malz and even Lucian if you can catch him. Plus since his moves aren't very flashy a lot of lower elo players don't even know their stats got robbed.
He's not a very good all around pick but he's like Sona in that he hard counters the champs he does counter, and he counters quite a few.
