Well, I do PvE of opportunity in my PvP blaster Hecate, like clone soldiers, relic/data sites, finishing 3/10 after killing the previous owner … BUT I definitely would pick a Jackdaw over it for pure PvE. Hecate with rails may be an valid option though.
I’ve used it as a hacking ship in low sec. If your hacking and probing skills are high enough, you don’t need the bonuses from the scanning ships like the Heron. It’s good for shoving aside competition or killing AFK pilots.
The blaster Hecate is also good for blasting the tier 1 NPC ore haulers that you can find at belts. I think they drop strongboxes worth 30m isk. Kill them, bookmark the wreck, and warp out before the responsie fleet arrives, then return to the bookmark after a minute to loot.
Can do C2 anomolies quite well, as well as general lowsec ratting.
blaster dps means that any faction spawns or clone soldiers will get killed quick, and orbiting at 1000 with the MWD off will get you under the rat battleship guns.
And naturally insta-warp helps a lot for evading gate camps and the like.
