Okay so I recently started to level up the blade master and quickly came to believe it is one of the worst if the not the worst class in the game, Im aware the general problem on melee on higher difficulties esp on horde.
I know the class has a venom related bleed card which is unlocked at lv 15 and it could work well with the heal and get damage resist near bleeding enemies which is unlocked alot earlier and is essentially useless without the skill card on escape, and the melee bleed perk on horde is 100% needed to be able to do anything, the mode where melee classes are the least effective.
Also I am sure blademasters passive 30% melee damage resist does not work or is so low it makes no difference in game.
I can’t think of any situation where I would choose blade master over brawler or even protector for melee.
My opinions on the problems blademaster has:
Damage is not good vs any target outside of leeches and juvies which you can only fight one at a time as they can 2 hit down you without the use of the breaker mace and the bleed perk for horde and staying in venom with the bleed card for escape.
The ultimate ability is very lack luster and takes a long time to charge for its power, And in my experience does not even work properly some times, mainly vs ice and salvo scions as sometimes they do not get stunned
All elite drone types can one hit you and not be staggered by normal melee hits forcing you to hit once then jump away only for them to shoot and down you provided you can even get close to elite drones with their super accurate 2-3 shot claws.
Net code in PvE for melee can sometimes completely get you killed and ruin a run this applies to all melee classes as even the brawler class can try to tackle into a enemy only for it to teleport away out of harm.
Melee lunge is really wonky when it decides to even work .
The class has alot of usless skill cards that you would simply never pick and would be better as passives, this applies to a few classes not exclusive to blademaster.
Of course these are my opinions but i believe they are well founded and am happy for someone to explain to me if and why I am wrong and what could be done to bring melee up to the level of the stronger classes.
