Trap's never arm right away. Same with Nid's and Teemo's shrooms. They take like 2-3 seconds. Her pure damage output reminds me of MF before she was nerfed, problem is like MF. Not a lot of people are "skilled" enough to use her. Cait's a bit easier since she can get more map awareness and has actual escape. But right now, you have a bunch of people playing her who just don't pay attention.
Have to say, I'm in love with Janna. The amount of combo-ing up and denying I can do with her. I save ass hardcore. :lol
I still get idiots who think my shield makes them immune to damage, I can heal outside of ult, and my cooldowns are all 2, 3 seconds. I had an Ashe tell me how to play, and how I need to put all my points into shield right away to protect her. I asked if she just could stop getting caught by Xin and Alistar, stop pushing the lane, etc. Got called a fucking noob instead. Lost that game, Had one though with the same problem and a Tyr. He melted down and quit after I told him not to come back to the lane if he is going keep crying. "Mentioned something about good luck winning without me". 30 minutes later, comes back in and see's we still haven't lost any 2nd row towers, still have map control and pushed them back into their fort. We win anyways, just took a lot longer is all.
