So after all the complaints about the paladin I actually logged into the game to make a first test on level 4 missions myself.
Level 4 Pirate invasion took me 10 minutes, (That includes undocking → full clear, not blitzing → docking and turning in the mission)
11.29 million ISK + 4k LP
edit: While that is not an impressive payout, keep in mind that this is a mission that does not have a good ratio in regards to Time needed vs Payout
A Lv4 Blockade for example takes more or less the same amount of time and pays 20-25 million in ISK and 7+k LPs)
—edit ends here—
I could have done it faster, but I was using a double plated paladin with just 2 heat sinks and 218k EHP.
The fitting itself is not even worth 500 mil ISK and that includes 2xT2 Trimarks.
(Did not even have Turret implants in my current clone, but a mid grade amulet set)
No cap problems at all… never dropped below 50% cap and even had my repairer running more than I actually had to.
Even with that setup I can most likely finish a mission series like Enemies Abound in around 75 minutes (or even faster).
75 Minutes for 250-300 million without even going with a full dps setup and in high sec on top of it…
Seems broken to me, but not in the way ppl here claim.
