I hit a striker wearing wolver armor FOUR TIMES with a kamarin and he didn't die. Each time I saw at least eight bars of health fly out of him. He was also being attacked by the rest of my team simultaneously. Just walked right into the middle of us while we attacked him...
And then he killed my entire team, including me while I was wearing all quicksilver armor (IE high pierce resist) with two basic attacks from the 3* snarble barb. Basic attacks. Very high or Ultra damage bonus aside, you still shouldn't be able to kill someone who isn't a striker in two basic hits of a weapon they are highly resistant to without a recon debuff being on them.
Naturally he was the first one to shout GG when the match ended. Oh, that's nice.
And then, while wearing that same high piercing resist armor, someone else in chroma gear killed me in, guess what? Two basic attacks from a flourish. Claimed they used the charge attack. They didn't. They were a striker as well, but no wolver gear, so only a high damage bonus. That's only like, what, +20% damage? Against a highly resistant foe?
Or just, in general, the fact that my Sun Shards apparently does zero damage to all players regardless of armor or having the recon debuff on them, despite how effective it is against monsters. I get that I can't get the multi-hits against players for the same reason that the autogun series doesn't work in PvP, but just ONE of those shards SHOULD be doing the same damage as a standard bomb of its tier.
Or, people attacking at full speed while stunned. If I'm using a rigadoon and you're using a flourish, and I just stunned you, you should not be able to pre-empt my attacks when I take a swing at you first. That is rediculous.
Or how about people magically overcoming the multi-hit limitation, killing you with their second attack immediately after the first connects, when you should have still been invulnerable? With a minor attack speed decrease, the faster weapons still attack quickly enough that the second hit from the combo will be blocked by the multi-hit invulnerability. HOW are these people successfully getting in two hits in half of a second?
I'm not sure mercy invulnerability is even active in Lockdown.
That Striker, meanwhile, could have been wearing Heart Pendant trinkets to boost his health to outlast you and your team. Was there a Guardian nearby shielding and healing him?
