Not sure why anyone would want to use Lokke’s for solo questing. It’s main benefits only come into play in group content and so there are many sets that are better for solo questing. Similarly with Advancing Yakuda.

If you can get Lokke’s (ie you’re capable of running Sunspire) you should be able to do all the solo questing fairly easily. As the name suggests questing is more about doing specific tasks than facing the very greatest foes. And there are many more interesting questing sets for a stamblade depending on what you want your stamblade to be - stealthy shadow warrior, lethal assassin, vicious killer etc. My stamblade rocks a full on poison gearset with no trials kit, which is just lethal.

There’s really no need to gold out anything for solo questing. You don’t need to for most vet dungeons. You will get far more effectiveness out of good rotations and potion use than from upgrading from purple to gold. Then you will be advancing by improving your game rather than by improving your gear.

I would say just go out there and do some questing. See how your current gear works. Play with different gear. Increase your bag slots so you can have more sets to play with on the fly. Experiment with sets you pick up and play your own game.

Don’t play Alcast’s way because he tells you, play that way cos it works for you. If it doesn’t work, adapt it until it does or try something else.

Have fun
