Don't even bother with kraken stuff right now, as they are much too expensive to be worth it, unless you plan on spending every hour of your life grinding away. Arc 81s to be viable for most players should fall to around 1/4 of its current prices. Just aim to get a speedset (if you don't have one already), a decent gold loot set of at least 400gl (lucky you, gl belt+ring+pend sets are really cheap this month), and a mythic 81 set with both the gun and staff plus ebon arm. All you'd really need as of now are those.
