Lycan is most certainly not OP. If you look at the drafting stats it looks pretty bad at first glance since recently he's had pretty much a 100% pick/ban rate. However, if you look at the stats for 6.80 overall, Invoker has had by far the most impact in the pro scene with 90% pick/ban, a full 13 points ahead of the next runner up. Lycan is the definition of flavor of the month.
As far as TB goes, I would love to see where you got your stats from. There's no doubt the hero is strong, but his effectiveness in pubs is much higher than he would be in pro games due to how brain dead easy he is to play and how hard it is for uncoordinated randoms to deal with split push (which is what he excels at). I would say that Phoenix is probably stronger than him overall due to him being much level cooldown dependent, but Phoenix has an extremely high skill cap (similar to Ember and Visage) that won't really shine through until talented teams get their hands on him.
