1) What progression of zones should I go for, am currently in the lower levels of BOT...where next?
If you hail the custom zone teleporter she gives you a list of zones (which are in progrssion order if my memory serves). Ill list them anyway.
BoT > Plane of Time (Epic 1.5) > LDON (Epic 2.0) > FG/CG (Epic 2.5) > Qvic (keys you for 3.0 boss) > Tacvi > Plane of Dragons > HoHonor/Plane of Gods
2) Is now a good time to start FG/CG? Or are epic upgrades a better plan? Or is just killing in lvl 70 zones a better idea to get some better gear? Or maybe RoA?
In my opinion camp some pieces of the CG/FG when you are able to but its really not that important until you are ready to get your 2.5. Epic progression should be a main focus. You wont necessarily need RoA until Qvic at the earliest and may not need it depending on your playstyle. Also, it isnt until Qvic that your current set piece is required for the next progression piece. Dont be afraid to leave BoT/PoTime/LDON without getting all your pieces of gear.
3) How far can I realistically get to with my current 2 box set up?
Qvic will stop you dead in your tracks - I recommend finding a guild or making a few friends to group with. Otherwise succumb to boxing a group.
4) If I was to add a third box, what would you suggest? Tank? crowd control? something else?
Warrior is going to be your best option. However, if you are like many out there who dont want to play a warrior because everyone else does I still suggest a tank.
5) What's the waypoint thingy for in Surefall?
