Dexless all luk dit -- Yes or no?

is a base of 80 bad?

I can reset my stats at lv 120 if i wanted to with a cash shop item, right? i imagine by 120 i'll have all the funds necessary for godly dex gear, but for the time being it seems really difficult because i am still with my beginner gear.

80 is not that bad and would only be a problem endgame if you are a complete damagewhore and want to maximize every aspect of your character. When we recieved the potential system, and after that the new big bang formulas Big Bang, a few stat points here or there started playing a smaller role than before. Weapon stats combined with the potential bonuses is where the bulk of the power comes from. If you do plan to reset stats later on, know that it will cost you to reset it, 3100 NX per point (unless there is a sale, though that happens maybe 3 times a year).
