Exhibit A: Sometimes when you kill an NPC ship you get loot (given your not on a team with the Round Robin loot setting) and EVERYTIME you kill an NPC ship you earn BO skill points and player skill points.
Exhibit B: VAs and RAs seem to enjoy using these Sirius Sector Block DSEs to "test out" new ships.
Exhibit C: New players end up fighting in these same DSEs at the start of the game
Exhibit D: The RA/VAs could get a better test of their ships in the Beta Ursae, Alpha Trianguli, Zeta Andromedae and Gamma Orionis Sector Blocks than in the Sirius Sector Block. I happen to test my VA toon's ships in those sectors (mainly Gamma cos I like blowin' up borg

)
Exhibit E: (Wow I have a lot of points) I am rollin' numerous Lt. toons at present (and I expect I'm not the only one) and I don't really appreciate VAs swooping in and nicking the loot and XP from a BoP squadron that I'd nearly killed.
I submit to you, Cryptic, that it is NOT fun to take part in a DSE as a low lvl player, start blastin' klinks, and then having a VA swoop in and finish em' off before you even get a single kill. I beseech thee, please either block higher lvls from the Sirius DSEs (and any others that they've already passed, save the Borg) or give them a seperate DSE instance, similar to how the Fleet actions worked before Season 4. Or you can push all DSE participants into a team with automatic lvl scaling up so everyone plays at the same level, you'd also have to set up the DSEs to scale to that level like in the Remastered and Featured Episodes. (To save alot of VA flak the second idea would be the best way short of doing nothing. Shortly followed by my third suggestion.)
Questions and comments welcome, so long as it's constructive. Let's get this thread, and issue (assuming it can ACTUALLY be sorted), addressed by the Devs.
Thank you to SuricataFX for that lvl scaling idea.
