Them tier 4 skills....

Sup guys.

Soooo, what do you think about tier 4 skills? I wanted to make a suggestion, but then thought to post here first and see reaction.
Is the 55 skills requirement really needed? Because nobody uses only 5 skills somewhere (or at least I think so.. O_o).
I think changing it to 50 would be the most wonderful idea, that way you have to spend at least half points in that tree, and you get access to tier 4 skills. So you can basically take one tier 4 skill while still investing 4 points in other tree to reach that Tier 3 skill. So, just by adjusting those 5 little points, a lot of things can change.

But I guess preventing people from taking tier 4 skill from one and tier 3 from other tree is the point of having 55 points. But then again, why is it not 60 then ??

Opinions please. :D
