So, the Guild Event Store. This one's pretty easy except for the fact that there are two different types of currency to spend here. We have to handle them completely separately since there's no overlap in how you're using them. First is GET-2 (or "Guild Event Tokens II"). Yes, it's weird that -2 comes first, but it's at the top of the page, so it comes first.
GET-2 Priority List: 1. Malevolence Blueprints ONLY - NO GEAR
2. Negotiator Blueprints ONLY - NO GEAR ==> 5*
3. Switch back &forth between further Negotiator blueprints and g12+/g12-finisher gear as needed until Nego hits 7*.
4. G12+ & G12-finisher gear
5. Supplemental Kyros as needed, but always 2nd in priority to the G12 gear
Things are structured this way because you're going to get Geos first, and Geos + Malevolence is a lethal combination. I really can't stress enough how much 400 crystals per day from reaching 1st place in Fleet Arena can help you, and it's so much easier to reach 1st in Fleet than in Squad. But in order to get those crystals, you have to put the work into the high-end capital ships. It seems like you want to get gear here, but nope. In the long run, you'll advance much faster in **everything** if you have an extra 400 crystals per day. So you want to get to that level as soon as possible. You definitely want both high-end Cap Ships at 7*, but by the time you get there, there's always the chance that Finalizer or Raddus has become more valuable. IF that happens, and you have that other Cap Ship, then it's okay to slow down on the Nego farm. Otherwise you really do want to farm it as quickly as possible, with very few detours for g12 gear until you're done with Nego. The good thing is that once Mal & Nego are done, it's nothing but g12 gear & Kyros from there on out.
One additional comment about the priority of Kyros vs. G12+/finisher gear: you'll need more Kyros for some characters than the exclusive G12+ and G12-finisher gear, but for most toons they'll need 200 G12+ and G12-finisher, but only 100 Kyros (since most characters don't require Kyros except for their G12-finisher piece). It's easy to get caught up in how important Kyros are because for the best toons in the game you do require a lot of kyros (SLKR requires 700 by himself), but only of the characters required for the SLKR event require more than 100 kyros, so you'll need 2400 G12+ & G12-finisher for them, with only 1400 Kyros required for those same characters. That means for your requirements + SLKR himself, you'll need 2600 G12+ & G12-Finisher salvage, but only 2100 Kyros. When you put that together with the fact that emergency crystal purchases of Kyros from shipments are actually cheaper (700 crystals per 25) than emergency crystal purchases of G12+/G12-Finisher gear (875 crystals per 25), it's becomes apparent that you can't spend primarily on Kyros. You're going to need those other pieces.
The good news, after all that, is that with only the two capital ships to buy (rather than 4 toons, as you'll see below, for GET-1), you'll actually reach the gear-only stage a bit faster with GET-2 than with GET-1.
Speaking of GET-1, it's also a pretty easy list.
GET-1 Priority List: 1. Hermit Yoda => 5*
2. Check to see if you're getting close to ready for the GAS event or the Malak event. If you're getting close, start saving GET-1 for that character now.
3. GAS/Malak
4. Check again to see if you're getting close to ready for Malak or GAS (whichever you didn't do first). If you're getting close, start saving GET-1 for that character now.
5. Hermit Yoda
6. Stun Gun Salvage whenever you find it (any tokens above 5k you can spend on Wampa)
7. Wampa
8. Every Stun Gun salvage that you find here
9. G12 gear
Note that Wampa is required for Jedi Knight Luke, one of the best toons in the game. You should be earning Wampa shards through the Galactic Bounties event, but it's only 20 shards per event and the event is only once every 50 days or so. This is 0.4 shards/day or more than 2 years to finish Wampa. You're definitely going to need to buy some Wampa here eventually since you're very likely to be ready to try for JKL before 2 years are up. If you're thinking about JKL, it's probably a good idea to put the Stun Gun salvage on hold until Wampa is done. HOWEVER, if you're not ready to make a push for JKL yet, if you're only buying Stun Gun salvage you shouldn't be spending all your Tokens. You just don't see Stun Gun salvage show up in the store often enough to spend all your tokens on that. So your GET-1 will slowly increase, and once you're above a few thousand, you should spend the extra on Wampa even if you're not actively charging up for JKL.
