PvE only.
There is no real doubt that Warlock is best class in Alpha, zero. That could change and I wouldn't be surprised to see the Titan take the top spot. As it stands I do not see how the Hunter will ever escape the last place slot unless they do some hefty re balancing.
First off lets talk about Supers-
Warlock has the best, for two reasons. It is AE and it is ranged. You can jump up and lob it at a group of enemies without exposing yourself to damage. You are immediately back in the fight, using grenades and weapons.
Titan has a solid super that will probably turn into something that is 'required' for good group play. The problem is right now it is basically just a crappier version of the Warlock super. It is AE but you have to be in melee range to use it.
Hunter has the worst super out there. Three shots from a golden gun, wow.
Jumps-
Hunter has the worst, it is simply a double jump.
Warlock and Titan are really subjective. I prefer the Warlock, having the ability to hover far outranks the lift of the Titan for me.
Class trait-
Hunter is faster, this is something that could bring it up later in the game. Right now it doesn't make up for the deficiencies.
Warlock and Titan are again kinda of subjective. The Titan has more armor and the Warlock regens faster. Personally I like the quick regen much more than the extra armor.
Hence: Warlock>Titan>>Hunter
I agree with everything here. Warlock is my favorite. The fast regen makes me use my power and grenades more. Plus the upgrades to melee that reduces grenade cooldown.
But the warlock grenade is my favorite by far.
the damage over time grenade can wreck a high level captain even with the shields on.
It doesn't do a lot of damage on the initial blast like the titan's flash bang or the hunters fire grenade, but over all, the warlock grenade has the potential for the highest damage.
The warlock grenade is the only grenade i've used that was fully capable of killing a level 8 or 9 captain with full shields. And i also use it to take out one of the walkers legs too.
But the warlock grenade is the hardest grenade to use though out of the three. It takes some mastery skills to use right since the enemies are agile and move alot, making it hard to determine where to throw the grenade to have the most effect so the enemy would stay in it's field long enough.
The warlocks grenade is great for settings up traps, like those spawn areas though, areas where you know a whole group of enemies is coming out. I've used that grenade to completely block a spawn point doorway as the enemies are coming out of it and they are just dissipating as they try to get through it.
IT'S AWESOME!!! And with the fast regen time and the melee making the cooldown even faster. I use the grenade A LOT.
I unlocked the other options for the grenade, which completely changes the grenades behavior, think of it as a grenade mod from borderlands. The other upgrade i unlocked for the warlocks grenade is complete ass. its pretty much a borderlands mirv grenade, it explodes into tiny grenades that then explode again, but the damage is SO WEAK. I cant even kill a regular ass level 2 grunt with that shit.
