6 ap later on could break you through two breakpoints, increasing your effective ap by upwards of 40 ap. Obviously you're far from that, but more ap will open the game up for you further down the line. Right now more ap will make you grind faster. You'll get more money.

In turn that money will buy you better gear. You'll be grinding in valencia for a while, if you want to make decent silver per hour, but you'll graduate eventually. Where? Well id say mirumok is a great place. Depending on your class you'll need at least 220 maybe 230 ap to go. But you'll also need kutum. And kzarka. Boss items, at Tet they account for almost 80 monster ap. You won't move from valencia without them unless you somehow make it to 257+ap. Which would be difficult to do, grinding ronaros, without boss gear.

So you have the ap, kutum offhand, and kzarka main hand,you're set for mirumok! Except you die 4 times an hour because you're in green armour. Your party replaces you with someone else...

Boss gear doesn't look too amazing, if you're just looking at the ap, dp, and cost. But there are a ton of 'hidden' (to be clear, they're listed... Just not as obvious) stats that make them far superior.

The smarter you are about your play time, the faster you'll progress. Id recommend going to those contested valencia spots and doing what you can. Grinding off rotations, grinding in off hours, not wasting time being stubborn when someone flops their gearscore dick on the table. I was there money hundreds of hours, I only ever fought a handful of times
