Well, as usually perceptions differ. In my eyes pikemen are only supporters and nothing else. I don't know any class that is as much dependant on other players as pikemen are. Without teamplay a pikeman is worth nothing. On his own he can barely do anything. And on his own he is probably the most vulnerable class of all, with the least possible defense qualities.
Playing pikeman IS fun, and yes, it's a good supporter, but it's only a supporter. I don't say to buff him up to the level of cavalry or two handers, but at least the devs should stop nerfing this class from patch to patch, while constantly making bullshit considering the other classes, especially archery.
You are probably right, +2 dmg per loom level is too much, but buff the weapon otherwise, just to make up for the fact that it is the only class in the entire game where you can use only that one item. All other classes can go hybrid to a certain degree, pikeman can't. I think that's plain unfair.
