Hey guys. So after being in a pq with a low dex sin i wanted to become one but im already at 55 dex and to get all the way back to 30 would take alot of time and alot of voting. Should i just stay at 55?
Stay at 55 DEX. You'll need around that amount (or more) at higher levels unless you're very funded, there's no point on using resets.
You could if you really wanted to. Having Dex at a low level is useless anyway, but like @Aram said, you'll probably have a few levels of Dex later in the game for a nice end game claw. Keep it for now unless you don't mind spending the AP Resets.
Add DEX if/when you can't get enough from other equips to equip the end game claw that you want to use.
Your ideal Dex for an end game claw is 25 base. Get it as low as you can based on your funding. Add Dex when you need to add Dex. Collect all the Dex gear you can get at a certain level and work from there There is no set number of Dex you should cap at.
