So, after PvPing pretty regularly I finally filled out my 4 set bonus. Now, I've gotten such items from pvp that didn't add to the bonus but I needed them for my pve set so I felt them more important. Also, I thought the +speed boost was going to be underwhelming because (silly me) I thought it didn't stack. /cheer at my wrong-thinking.
50% Movement speed in cat. 97% with Dash. 61% in travel. 15% in bear. (Where's the aquatic form love? hehe)
After having these bonuses, I must say I'm truly so excited I put in the time! I've shown all of my buddies in-game already but I knew you guys would understand my joy, too :)
Imo, get your paws on a set of these if you are feral :D
