Oh yeah if you think WD is slow, then you haven't played Crusader. WD with the -1sec on every cooldown per kill and spirit walk isn't so bad, as long as you stop every 5secs to kill a pack of shit(so they suck when there's low density, but you can more or less keep running with spirit walk if there's large packs and a lot of them). Crusader is shit regardless, with your best bet a cooldown that moves faster than spirit walk but has no way to be reduced besides CDR(other than Akarat Champion, which is a 90secs cooldown itself) and since the base is 25secs, even with a solid 40% CDR you're still looking at 15seconds, more than spirit walk base cd. Oh and if you use a 2H, which really synergizes well with your cooldown based nukes(bigger damage per hit is better when you can't spam a skill), then you're double fucked since you move 15% slower all the time.
They overnerfed the horse, or the 2H talent, or both. I think the 2H talent should have a DPS penalty instead to further reinforce big hits vs damage per second, say like an attackspeed penalty but the movespeed reduction is crippling when trying to farm. And horse needs to not suck, 2(3 with a rune) of high speed on a 25secs cooldown is ridiculous. Teleport Wormhole is on 16seconds(and there's a passive to decrease every cooldowns by 20% as well as another that resets the cooldown on teleport if you get hit for more than 15% of your life), Spirit Walk is on 12secs(and there's a passive to reduce cooldowns based on kills), Dashing Strikes is on a 8 secs "cooldown" and there's a 10% movespeed passive that goes over the cap, Sprint has no cd but requires ressources, which can be generated with a 2nd skill and a shitty rune as well as passives, this one is meh but it can be sustained and finally DH don't give any fucks and more or less have permanent 60% bonus movespeed with Tactical Advantage.
Only redeeming feature is once you have 6pc bonus of your class set, you get a 50%reduction on Akarat cooldown, which with more cdr shoud drop it around 40seconds or so, it lasts 20secs and you can rune it for 30%movespeed, meaning you'll be running fast half the time, which is pretty cool. But like 6pc class set(or well 5 with the bounty ring) is crazy requirements to have "decent speed". Also there's a shield that removes the penalty for 2H, so that makes the class a bit less crap. Could also use a 1H instead, but you lose quite a lot of damage potential I feel if you do.
