Why do you blame Pantheon's rework? Seems fine to me
Well, this one time I bought Pantheon to the Twisted Treeline. Actually, it was my first game with him reworked and I played him on my birthday. I lost, but it was still stupid. Because
got 30/0/2.
And then one day I met a 63 thousand mastery point Panth. He didn't get a single kill. He got the points from old Panth.
Looking at some of the comments, I guess the rework only worked out for some people-see poll below.
Note: Snipe with q as much as possible. And play quite a few games with bots only to improve.
