Mergen skills have the same CD as Circling tho… Spread Shot is on a 36 sec CD, Triple 30 sec CD, so cooldown isn’t really an issue there.
I’m an Archer2 Ranger 1 Scout1 Fletcher3 Mergen myself, full Solmiki, and honestly what carried me through the Solmiki floors isn’t really the Mergen rank… it’s all about those Fletchers skills (Crossfire/Divine/Magic/Barbed), with how unreliable hitboxes are on Mergen abilities (I lost count of how many times Spread Shot have hit thin air due to movement/positioning).
Also, you have to consider what you’re losing by investing in that juicy AAR, in my scenario it is atleast 72 Crit Rate, 818 Physical Attack (+30% from Glassmoles) so yeah, honestly I’m not really sold on those Centaurus cards right now…
I’m quite in a inner conflict right now about the future Mergen2 rank, if it’s nothing mindblowing I’d probably see myself going for Falconer1 (and delete a free penguin for the Hawk).
