I don't even know which faction is the favourite and it doesn't really matter; this game is fun, and that's all that really matter to me.
But in my short experience i can say that, as a Chaos player (if my avatar wasn't a hint
I was thinking about it and i believe the problem is that every unit in the Tier 2 of Chaos is very situational (that's not a bad thing) and have a very little "safety margin".
Except for the obvioius Dreadnaught, that is predictable, all the other units have no upgrade for change their role in combat.
They are not bad units, but have little to no flexibility.
I really like Noise Marine for example; a flamer unit that can change in a heavy plasma one. Awesome.
Plague Marine don't. They rest as a very situational and slow AV.
Bloodletters are a jump units that i still don't quite get the difference with raptors.
Bloodcrusher is a unit that have a very short span of life. You can do lot of damage if you rush it, but then it has no place and rarely get in Tier 3.
I read about a subcommander for Chaos and i can say that i'm completely against it.
I think there is potential for a more dynamic Tier 2 just with upgrades for these units and there is no need for a new unit.
(but a Dark Apostle of Slaanesh as a forth Commander... i'm ok with it)
A Tier 3 upgrade for the bloodcrusher that give it a place in late game combat would promote more experiment with it in Tier 2. A teleport/leap? Some change in type of damage? Health and regeneration? Damage resistance during charge? I don't know.
But still, knowing that a Bloodcrusher may be useful in Tier 3 with a new role will allow players to play them more without feeling is a gamble, and find a role for them until they get that upgrade.
Bloodletters are ok, but they may enjoy something to differentiate them from raptors. Maybe the Collar of Khorne, and give them some energy leech into life ability, so they become a more "anti-energy units"" type of jumper. I still don't know. Just brainstorming.
And final, my favourite, the Plague Marine.
I believe they could have some upgrade to become a slow and metodical melee unit. Give them, for example, an upgrade for switching to Plague Knifes so, like Noise Marine, they can change their type if they become obsolete.
Probably some of these ideas are garbage but i still think that some of them are rarely seen and the gameplay may benefit from some extra options, expecially for the bloodcrusher.
Thanks for reading.
