A1S/A2S have been doable since 190, A3S should be fine with current gear, and A4S should also be fine due to the sac strat. 6x WAR + 1 DRG + 1 SCH/AST/WHM would be the optimal comp for a full Savage run through, though you may need 2x healers for A4S. A1S-A3S are pretty outgeared now (was doable week 1 which means i185~i190), and I'm not actually sure if A4S is possible with the intended Nisi strat or not but I doubt they'll be doing that method.
Assuming your complaint is "WAR does too much DPS!", then I think you're partially right and partially wrong. A1S, as an example, was doable in i190 for the aforementioned comp. The reason for this is the fight was tuned so low in terms of DPS that WAR's was good enough to beat enrage while providing excess mitigation to make solo healing it even at such low gear levels possible. With that tuning, WAR's DPS is genuinely too high. However, if the DPS check was tighter, as seen in A3S, we'd no longer be able to just throw WARs at it and kill it at the same speed as a normal comp group would. So the easiest way to avoid WAR stacking is to make tighter DPS checks that wouldn't allow for it until exceptionally overgeared.
However, considering the fact that they want to make the next raid tier "easier" that can only mean loosening the DPS check, which will make WAR stacking once again viable. But they'll also be changing the damage formula for tanks in 3.2, so the meta could shift entirely if DPS is balanced.
Right now, for A1S, A2S, and Thordan EX, at the gear level we entered them in, WAR's DPS would have allowed you to reliably class stack them. Thordan, as I mentioned before, is also doable with PLD/DRK just at a slower time.
So, basically, if you want to complain that WAR does a whole lot of DPS in current content, then you'd be correct. I understand the worry for 3.2, I honestly don't like how the future is looking for DRK or PLD if things stay the same, but we won't know until we get there.
