I too am a movespeed convert. I was ready to give up on Goliath being a buggy mess but this perk has brought life back to him for me. Also been using it nonstop on Wraith since the perk patch – her Supernova melees feel so fluid with it. Undecided on Kraken and Behemoth, though. My reasons:
1). Makes it easier to escape Sunny+Griffin.
2). Makes it easier to eat and evolve and get to buffs faster.
3). Makes it easier to get to favorable terrain when a fight is coming up.
4). Makes it easier to keep melees on the Hunter you want to focus.
5). Additive with tranq/stasis and not multiplicative (this might get fixed).
6). Sneaking and juking are faster and it directly counters a Maggie pick.
7). Fewer missed heavy attacks on wildlife (grr).
8). Makes Trapper 25% more angry.
9). Gotta go fast!
Yeah it doesn’t affect the traversals and movement abilities, but after the patch I feel like there’s no other viable option with all the nerfs. Before, I would consider traversal if I knew it was Torvald, or damage or cooldown or sometimes even feeding speed as other general choices depending on the map. Now? Movespeed 100% of the time. OP? Probably. But it’s allowing me to finally have fun against the godcomp, so pls no nerferino!
