OE'd tsu*sls or +3 MS w/Focus for 73+ grind

warning: noob question up ahead.

recently hit 73, and have been using my OE'd duals to grind (+14 crit augment), they have worked wonderfully so far, never really needed to use stun when PVEing.
now contemplating on getting a blunt, a M.Shower w/focus to be exact. i was doing research on L2Calc and with buffs, i've 184 crit rate on duals. if i'm able to get the same augment on a MS w/Focus the crit rate will be around 140 (pretty huge difference). but the atk speed is much much faster on the MS compared to the tsu*sls.
so worth buying the MS, or save the money to get the Basalt later on?

/TY for any advice.

Save money and get the Basalt later on ;)

Consider Meteor Shower with Focus still out damage basalt batltehammer with buffs ( unbuffed it's more granted ) it's up to you, S grade shots is also very costly.

It's on other hand a nice weapon if you combine it with health for PVP, but for raw damage it's not truly the best.

basalt sucks for everything except olympiad
and i'd have to check L2calc to see if meteor is actually better next chron since you get buffs
