The brackets like they are now make sence for a new mmo.
You basicly dont have alot of lvl 50 players yet and the system they use which is almost the same as in Warhammer to boost your stats really help lower lvl players.
Cross-server BG that you are revering to like in WoW made BG in that game more boring then it ever was.
You didnt build up any form of social contacts on your own server like you did during the proper BG's on your own server.
The CC might be a bit to much yes only thats a balancing issue which can be changed by future patches.
Every new game has balancement issues.
Bit like WoW had a nice balance issue at the start of TBC where they made warriors completely useless for tanking.
And still TBC is the best expansion they ever released.
Untill now you can also use CC yourself on for example the DPS, or boost up the survivability on the target thats being killed.
I know this wont happen much in random warzones only thats a problem by the players not the game mechanics.
"but how can it be (in my opinion at least) worse than, say, a certain game that came out 7 years ago at it's own release? "
Funny how you are revering to wow here.
7 years ago WoW had close to no pve content.
WoW didnt have a single BG untill patch 1.5
The only way to get honor back then was through world pvp.
And lets not forget how awesome balanced the classes were at the start of WoW.
sarcasm intended.
