I honestly don't really care about the tier list, I just find it funny that people take tier lists seriously. Sure, one can take them seriously because they're 'valid' in their explanations on why one unit is leagues better than another, but eh. Up to each individual on what they wanna do.
While people are up in their tier lists, I'll be sittin' here just playin' the units I like to play, and using them in Arena. :P
