I just want to make some simple suggestions using this format:
Tier: #
Evolves from: [Name]
Name: [Name]
Uniqueness: [Description]
Ability(s):
[Ability]; [Description]
It's strengths: [Description]
It's weaknesses (for balance): [Description]
Let's start with my 3 suggestions:
Tier: 3
Evolves from: Spitter
Name: Glider
Uniqueness: Is like the xeno version of CAS, except with acid gas blobs.
Abilities:
Far-sight; (like boiler's)
Take-off; (self explanatory)
Bomb; Choose a direct to carpet bomb with gas from your position.
It's Strengths: ... do I even need to explain this? You also can't hit it in the air.
It's Weaknesses: Returns to the EXACT position from where it took off. Slower than a hive-lord. Low health. No questions ... and no way out of a sticky situation you ... heh ... LAND yourself in. Has a cooldown for flying of 60-80 seconds, so a boiler can pump out 3-4 times as many deadly abilities per second as this thing.
It's kinda like Ridley from the metroid series ... except with acid not fire. Has a big-ass shadow looming over where it's gonna bombard and perhaps a loud banshee screech (Like CAS).
Tier: 3
Evolves from: Lurker
Name: Wraith
Uniqueness: Abduction from ... you guessed it ... the Wraith monster from Evolve.
Abilities:
Far-Sight; (like boiler's)
Dig-In; (like boiler's)
Abduct; While in far-sight, middle click a target you want to abduct. You rush up REALLY FAST, grab the target, and go back to your original spot REALLY FAST.
It's Strengths: Does loads of damage. Relatively fast for a T3. Has the capabilities of a warrior on steroids.
It's weaknesses: Low health. Doesn't stun the grabbed target "THE FUCK YOU SAY TO ME YOU LITTLE WRAITH!?!" *PB Buckshot*. PB Buckshot should almost
instakill it.
Is basically like the Wraith from evolve. Does high damage and is incredibly good at securing targets, but should always stick with a xeno that has some type of stun-move ... unless they want to get PB buckshotted or absolutely wrecked by a incendary sniper round followed by the abductee CHASING it and killing it.
Tier: 3
Evolves from: Lurker
Name: Obscurus
Uniqueness: Melee DMG crowd-control.
Abilities:
Anger; Boosts damage output for about 6 seconds. Re-charge of about 20 seconds.
Gehenna's Rage; You Ascend/Descend into a pure rage-induced madness for 5 seconds. You are invincible during this time, you but cannot move as your core is spinning on the center tile and any movement by you will tip you off balance. You slam any and all marines that come within 2 tiles of you to the ground during the whole 5 seconds, dealing damage. If there is anyone within the 2 tiles of you at the end of your rage, you wind up your claws and fling them away from you, dealing MASSIVE damage.
It's Strengths: Decent speed for a T3. Deals absolutely INSANE amounts of DMG to marines who are grouped up, along with invincibility, you are ... preeetty damn scary.
It's Weaknesses: Marines can be dragged out of the 'storm' it kicks up by just dragging near the edge, so only people right next to it are fucked. Has such incredibly low health ... well ... let's just say a PB buckshot would insta-kill it, not hard for a determined marine willing to push.
