Questions from a returning player

[Vaer]

I would go to Void Ark(i175)/Weeping City/Dun Scaith, make your way up and start rolling on the gear to gear up while collecting the upgrade tokens. (a set of 3, one clear from each area needed for one upgrade item to upgrade from 260->270) Grab the 270 accessory quest for Dun Scaith when available. Should be easy as a tank since there is no competition. Void Ark at least has a very high completion rate, it is pretty much faceroll at this point. The other two can be a bit tough.

Supplement with the daily roulettes and buy some lore/scrip gear if Weeping City/Dun Scaith ends up too annoying. I would start with the right side to get ilvl up quicker.

Finish all the alexander normals up to the last one once you get enough gear doing dungeons/roulettes and the above, get gears to get a micro-tomestone, spend the 1000 scrip to get the weapon tokens to get the weapon (260) then one set of the upgrade items mentioned above to boost it to 270. Should be set for the weapon then. Since the scrip cap is 900, you don't have to buy this first.

If you need a weapon to tide you over you can get the old weapons that are on the hunt vendor or do the first couple steps of the relic.

Alternatively you can go do PvP and get the event set which is adequate for most stuff. (It's around i235 which would be a big boost) PvP syncs you to a very low ilvl so no problem there.
