What's the consensus regarding progression? What's the most efficient way to level up and gear up? I saw some players saying that the ideal is to spam PQs while queueing for SCs.
There are a few problems with the above, there aren't a lot of people trying to do the PQs (LVL 15/12 Chosen here) and I blow hard on PvP, don't know if the reason is that I suck hard or just lack of skills/level to fight on an equal level.
For leveling up it seems that PQs while queueing for SCs is fine, because apparently the quests give **** XP. But what about gearing up? Is there an ideal progression? Level Tiers or something like that?
Usually MMORPGs have specific tier sets based on levels/tokens(made up names):
Tier 1 - Set of the Donut Eater
Tier 2 - Set of the Soda Drowner
Tier 3 - Set of the Burger Grinder
Tier 4 - Set of the Pizza Devourer (usually everyone fights through the tiers just to get this one)
I think you all know what I mean. Is there a BiS or something that I should focus to become competitive or just to face endgame stuff? Info like ideal accessories, etc and even build for Chosen (trying 2H) are welcome too!
