Threats to Zilean with this build
|Braum||It's usually, as Braum hasn't much mobility, and the only leap he has gets him close to an ally making them both easier to stun.|
I have been one of those guys, who hated Zilean, thinking, he is useless until I played him for the first time. I have been maining him for some time, and now I'm trying to make Zilean the most respected support EVER!
Be confident and use your autoattacks. It works really well with thunderlord's decree and spellthief's edge. Remember, you don't have much mana, so don't waste it on zoning. You need to make sure you can land your Q. Obviously, your combo should be: E-Q-W-Q, or simply Q-W-Q if your enemy is slow. If you see an enemy close to low-health minion, drop 2 bombs on it. It will kill the minion and make a damage of 2 bombs not leaving your enemy any time to use shields. If your enemies are in the middle on a minion wave, put bombs on minions, they are less likely to dodge it :D.
Roam. Your ult works wonders. You should have lots of mana and tear of goddess, so keep spamming your abilities. If enemy catches you while roaming and gets close to you (like Zed's ult), land your bombs on YOURSELF, not your enemy, it will stun him with co chance to dodge it.
While teamfights, try to land your bombs on the middle of their team, or on the ones focusing your ADC/APC. Try to keep your ult for the strongest of your allies, preferalby juggernaut/bruiser, but don't be afraid of ulting yourself. YOU are probably the one with the most CC's throwing AoE stun every 4 seconds.
