The good: lost city, graphics, homebuilding, roles and skills, weapons, except melee, the bionic gun, crafting in particular, the ease of farming (where is the farming skill?), strongholds.
The bad: most quests are boring, most dailies are tedious, not to many options for solo, only a few ways to gain xp, server caps, limits on selling items, material upgrades by level instead of one material for all, recon mode, melee is an afterthought, no real looting or excitement about getting rewards, all drops are basically the same, little nuance. The sniper rifle is great but hard to use in strongholds due to the regenerative nature of every npc. You try to do a mission and the same boss keeps regenerating nearby. After killing him three times, I gave up. The game has lots of promise but now we are waiting 8+ days to gain a level. This is not a good way to slow down forward progress.
