Q:
TITLE BONUS'
This is a good idea and some other mmos have something very similar. Good incentive imo, without any imbalances!
Was a while ago, but in PvP in WoW there was a little something we got as we moved along and our titles changed as we won more and more. We could have it be stats, or a bit of gold. Just something for our achievements. People are more motivated when a little extra is included. It could be something as simple as a point or two permanently added to one of our pieces of armor. Say , easy title gives 1 or 2 stat points, harder one 3-4. Your choice on what stat and which piece of armor/weapon it permanently placed, Would be a nice collection of titles with stats and probably more would work for the titles.
The addition of some extra armour and weapon skins would be a better option here I feel.
GW is “supposed” to be horizontal progression, which means instead of hunting for stats, you hunt for cosmetic changes.
Add skins to achievements, and voila!
