I think it would be a very good idea to look at adding variety into weapon skills as well as minor traits it may add more need for balance but help with it some as well. Such as address the problem of p/p the #1 skill is a poor choice when traiting for damage but could be changed to a different skill. Such as one that shoots at a decent pace with perhaps 1 stack of vulnerability. I could switch my #5 skill for more of an evade skill, perhaps with my d/d set up change my combo skill to more of direct damage skill that would be good damage with a vuln. and chill. Swithing minors would help alot with build diversity as will like changing my serpents touch with stealing gives you a stack of might for 10 sec.
Of course these are just some examples for a thief but I think some more build diversity for all classes could be good but with the thief it would be a really big deal as some of are weapon choices are very restrictive and would be nice to be able to change are combo’s as well as our stealth skill to fit the roll/play style we are looking to fill.
