So the thing about Berserkers is that I don’t see any point in using them for melee.
I give them laser AR and use them to safely strip armor from big baddies from long way away [I don’t use rage burst, because it’s an exploit: berserker’s ability to shred armor using direct fire weapons I consider bordering on exploitive]. Actually, I don’t want them to be too close to their target because I want the lasers to hit as many body parts as possible to strip armor from all of them.
I have read and I can imagine many other combinations, some of them quite OP and gimmicky (like not healing the berserker so that he keeps the damage boost from blood lust, blood lust that he indulges in using a cannon or sniper rifle), but one thing I don’t see is a berserker in a melee.
With that in mind I suggest the following changes:
Fix melee (see this thread Melee weapons balance)
Replace “armor break” with “charge”: ability to appear on any tile next to any enemy within 10 tiles and attack with a melee weapon, all for 3-4WP and 1-2AP.
Make berserker melee attack always shred armor
Rework blood lust so that the boost comes not from health loss but number of attacks from enemies.
