Why do you think obsidian gave them no late level abilities ththat are any good? Thats because they thought they are overpowered.
This is almost never a good argument. Game devs may know actual mechanics of the game better, but they are seldom better players or better judges of game balance than the top players - in part because they seldom spend enough time actually playing the game at high levels than the most dedicated players (who often try to find ways to break game or find exploits). While I may be a neophyte at this game, I've played enough games to know at least this much. In fact, I have been part of high profile raiding guilds across several MMORPGs (including one that consistently was among the earliest guilds in the world to down the initial WoW bosses) and recall devs had to patch stuff constantly, because bosses were being downed in a manner that was never even foreseen. Heck, I recall encounters where multi-stage bosses were essentially put down almost instantly in the first stage, because the top DPS-ers in top guilds were able to achieve DPS numbers that the devs thought "impossible."
Long story short: Devs are not only infallible but usually more fallible than the top players.
Edit: A rather telling story about how a lot of WoW Warriors quit and re-rolled even before the game went live (!). Initially, Warriors were envisioned by the devs to be a "tanking" class - while Hunters and Rogues were supposed to be the single-target DPS specialists. But we beta Warriors knew in practice this wasn't true, and that there was a less popular build that could stack a lot of unpopular talents to achieve the type of DPS that would blow anything Rogues or Hunters could achieve right out of the water. Unfortunately (for us Warriors), one of the beta Warriors insisted on fixing this issue and kept telling devs that Warrior DPS was OP and certainly not working as devs intended. The devs kept telling him that he is wrong. So the guy made a video that went viral and showed his Warrior two-shotting the entire (then) end-game outdoor content.
So Warriors got nerfed before the thing went live, and a lot of Warriors got angry (though the nerf was obviously needed). And devs were publicly embarrassed for being blind.
Needless to say, it wasn't the first time WoW devs would mis-diagnose end-game balance.
