Hey,
I went through the game once as a tempest archer(blackwall as champion/tank, solas as rift/dps, vivienne as KE). The tempest playstyle wasn't a lot of fun and am sort of regretting not going assassin or artificer. I'm going to start a new game on hard or nightmare. I'm considering playing reaver warrior. Is it a similar playstyle? If anyone has some time and expertise and could breakdown the playstyle of the various classes or specializations I would really appreciate it.
Reavers have less utility and are more aggressive than tempests. As a reaver who has done solo NM, it is ALL about timing of abilities, as devour and RoP will drop your stamina crazy fast if don't know what you are doing.
As far as healing gear goes, just have a superb heal bonus belt and maybe a heal bonus on your armor upgrades, if necessary. This will help out your devour significantly. Dragon-rage and RoP are your bread and butter. The RoP upgrade and dragon-rage are essential when facing a mob. However, if you single out a target in the mob, do not use RoP or dragon rage. Chances are, the rest of the mob will reach you right after you have killed or are about to kill the target, which is why you need to conserve health and stamina. You want to control to the best of your ability the damage that is coming your way. The turn the bolt/blade passives in the SnS tree will greatly help with this, as will Block and Slash. Group work is fairly easy, have your tank aggro and you won't have to worry too much about being the main threat. Go solo, and this is where you have to really pick your targets wisely. A lot of other reavers like charging bull and challenge for a little guard and stamina regeneration, but they aren't necessary and can be replaced with better passives and upgrades. Guard on a reaver in NM will barely last unless you have guard on hit gear. The same can be done for stamina, fade-touched great bear hide and a superb amulet of stamina will give you all that you need on solo NM.
Compared to tempests, reavers can have a lot of different playstyles depending on your build and will use a different number of skills as an effect of this. On my build, I use every ability I hot key except for my focus on solo runs. I use 3-5 on group runs. Reaver is not a 2 key class.
Edit: Reaver is more about sustained Dps rather than burst. Burst dps in warriors can be achieved through the templars WoH+SP combo. Although that combo does have a fairly long CD.
