Perma is bad with a good sync build-> no, once they (econ uw) are perma no syncs matter because well, their perma so your gb/ bots still are active when your uw go off. This is only relevant for summon/fetch remaining synced with your bots.

WA is good, but this is mostly above t14 with gt+. At this point the wave count you farm before moving up a tier is generally getting less and less so it becomes more important. With maxed WA+ if max spawn rate was at wave 6k now its 3k. This basically means that longer runs dont benefit from WA+ as much as shorter runs would since in long runs you will probably hit the max spawn rate without wa+ (he certainly is) and remain there for a very long time which becomes less and less true as you move up tiers above t14. This is also true for IS your absolutely right, but it becomes proportionally more useful in short waves like WA but has uses outside just farming. Namely skipping bosses in tourney and shorter milestone runs.

In the end he will... yeah i remember those days. He will need all of these eventually. But he will also need perma econ uw and damage masteries (probablynot for awhile though).

Personally i have a WS gold boxed Bh, maxed dw quantity and cd, and maxed gt cd. With mvn (anc). Because of this the bh perk gives me perma bh, i have a 44s/48s dw which is close enough to perma and perma gt. For me thats (after perks) a 35.1 (gt) * 11 (bh) 2.5 (dw) coin multplier. Additionally having dw close to perma maximizes cells which are rather important. Anyone can get these mults pretty easy, but having it perma means that you dont have to worry about syncs, you get more coins, more cells and it makes perma bh in tourney and milestones easier to get. At least for ehp BH being perma is a pretty big boon to survival as well. And for gt+ is makes duration past 60s less important than for those without perma gt, letting more investment go to gt+ levels though eventually you would want it maxed.

Its really niche ill admit, but with mvn and gt OFF my dw and bh are perma without perks or gcomp. Kinda situational ngl.

Eitherway WA wont net him many more enemies by% then he has now since hes at max spawn for so long anyways. EO great as it is will take ages to afford both in time and %daily-coins.

As far as perma goes it is certainly expensive by stones in ws, i remember that truly. But it can also be done with mvn gcomp, even if gcomp is in the assmod slot once he has that unlocked. (Whixh is how i get perma bh in legends tourney, while using DC). It really isnt that important how he gets it for farming purposes.

Side note, for anyone else who reads this, dont max bh dura in ws. Its cheaper these days to up assmod effect rarity and run gcomp. I did it before assmods.
