Well, yea its obviously not a big secret, and probably like you said their biggest problem.
I know I dont have a good computer but, i am able to run well WoW with high graphics whitout laging. It takes me some seconds to finish a loading bar.
In Swtor, some planets like Corelia literally takes 5 mins to download with everything at very low. So pretty much, when i am on these planets, i cannot Queue for a Wz even if i want to) because its WAY too long to dl the map. This problem actually stopped me from leveling alts.because i love to PVp and lvl at the same time and i am not patient enough to wait 5 mins between each wz.
I agree with your post even tho i dont think they are gonna change anything soon.
