Pure has been working extremely well in heroics for me up to now.
Only level 13 though. Points evenly divided between Soul Eater and Tainted Scholar at the moment.
First thing I did was rush to Cone shape early on and everything has been a joke since.
Feats...still not sure what would be best yet. Took emp/max/quick early on but feels like I don't really benefit much from them at the moment. SLAs are all I use them for and they were powerful at the early levels but have not been that useful since Blast has been more than enough to murder anything when cone was acquired. I can see them being useful again for Destiny spells, so picking them later might be best.
Else than that, some spell focus to unlock ED +DC stuff probably, might consider Extend for Displacement/Tenser (if that does not screw up refresh on Destiny things, idk yet have to test). Maybe Mental Toughness line for spell crits. Still very undecided about a good feat setup

As far as splitting goes, made me consider maybe adding Warlock levels to my Shiradi Druid build if I ever run that again. Feels like a lot of procs could be added with the aura tree and those two AOE blasts in there.
Hope it can help a bit, sadly not very experienced with them still.
My first try with warlock:
20 warlock, drow, true neutral. Picked fey path. Majority of enhancement points in Soul Eater, with the remainder in Harper. Went charisma based.
Pros:
Once you get cone shape around level 4, heroics are a joke. I breezed through heroics, just using cone shape aoe attack. The SLA's are ok for more single target dmg, during a boss or whatnot, but for the majority of the quest, all you need is auto attack with the cone. If you pick up the triple blast enhancement sla (forgetting name atm, just got home from work), stuff dies even faster. With disco ball, auto attack, and the triple wave SLA, even kings forest Grim Disturbance was quick.
Cons:
Squishy. Kinda meh in ee.
Feat wise, I had the maximize/empower/quicken for the SLA, and it is ok for beefing up the dmg for boss/single target. I also took the spell power line for spell crit, and am in shiradi ED. Seems to be... ok. Definitely more AOE dmg than 5 foot's pure barb build I've been running for many lives now, but I think that is still more fun and definitely has more survivability.
My next life, going to try PDK 20 warlock, going melee 2wf, with PDK char for attack, and using the enhancement line that changes EB to an aura, and has 'cleaves' built into the enhancement line.
