Titan's Grip decreases your attack speed by 20%, not your wielded weapon's speed by 20%.
That means you do not only lose 20% of your weapon's DPS but also 20% of your DPS you gain by AP.
In full Sunwell gear your average 1h Weapon DPS is ~110 while your average 2h Weapon DPS is ~143, so you'd get a (143/1.2)-110=9.17 char screen DPS buff from the changed weapon but reduce your char screen DPS from AP by 20%, so if you have more than 9.17*14*100/20=641.9 AP, you will actually lose white DPS, I believe even your naked base AP with Battleshout is higher than that.
That said, what are the benefits of it?
Usually same tier 2h weapons have 30% more DPS than their 1h counterparts and are 37.5% slower (tested with S1-S4 weapons).
So the Whirlwind/Slam "weapon damage" formulas are, assuming same tier weapons and dps/speed refering to the 1h weapon stats:
1h: dps*speed+ap/14*2.4
2h: dps*1.3*speed*1.375+ap*3.3=dps*speed*1.7875+ap/14*2.4*1.375
Assuming that you usually get at least the same and a maximum of 4 times the amount of DPS from AP as from your weapon, that means a boost of 45.75%-58.125% in weapon damage.
Assuming your decreased rage generation is enough, you'll also gain more effective damage per rage from Heroic Strike and Cleave in raid situations, as most of their benefit (if you're geared properly) is increasing the damage of the hit percentually by reducing its miss chance by up to 19% (HS and Cleave) and giving an additional weapon hit (Cleave). However I suppose this is mostly countered by the decreased rage generation.
Of course you also get on average 1/(27/64)=2.37 times as much stats from your weapons.
When you put together above points you get:
+ ~137% weapon stats
+ ~8.33% weapon DPS
+ ~50% Slam/WW damage
+ increase in Cleave/Heroic Strike rage efficiency
- 20% white DPS from AP
- ~18% rage generation
That's assuming you put 5 points into it, I wouldn't even want to look on the numbers when you don't.
Now this may look as it's a pretty good talent, but as in endgame raids you usually have ~70% of your damage coming from white hits and Heroic Strike or Cleave and ~70% of your DPS is from AP, it's not really looking good as a 5 points talent.
