New Trundle is OP. I love him. Dude is near unkillable 1v1 with BotRK and his W and R. He can also take down tanks pretty quickly. Spirit Visage is also fun on him if you need some MR and are snowballing a bit.
I've actually been running "heal" on him instead of ignite when i feel like im playing against a champ I cant kill in lane
500+ heal later in the game with spirit visage and his aura, not to mention the AOE heal is pretty solid in team fights
