Skill Trees were gone in 3.0
What difference does it make? It's just easier to gear via FPs and OPs (non token drops). Either a DPS/Heals drop or tank drop. If you don't even raid or do FPs, then it literally makes no difference unless you just liked seeing Aim, Cunning, Strength and Willpower on your character screen.
This is just complete misinformation, because no where near half were removed. Some tiers had 2 different types of the same materiel, ie, 2 different metals and 2 different compounds, which led to one of the two being under utilized. They decided to CONVERT those materials to the other type.
You still can until you launch KOTFE. Why? Because once you do that, there individual stories make no sense, so when you level a new toon, you still can do companion quests.
Much better this way, if I wanted to gear my companion, I'd play Pokemon
Not sure if you are serious, people are still doing it.
They warned us....besides how many half done missions could you possibly have, willing to bet you are just trolling at this point.
Can I have your stuff?
