Fun deck, not for laddering though. Maybe if ladder was priest only, lol.

What sort of issues did you experience while playing it? 

Too slow for OTK, too slow for aggro, too bad for Rogue in general. Warlock control has no place in this meta with lack of healing, especially if you go highlander and can't use soul shards.

I agree with you: the playing pace is slow, it lacks healing. However, it has a lot of removals, taunts and some heals. My list isn't perfect, but - judging from the player feedback - it is getting perfected. I'm lacking cards, lots of them, so I couldn't finish the list properly. I got a reply that it works much better with Siamat, Dragonqueen Alexstrasza, Nether Breath, Crazed Netherwing etc. Maybe it does, maybe it doesn't. What is important is the concept. If Barrens expansion proves right, the concept might stick - not as a Highlander, but as a fine control deck, especially with the new Old Gods.

I agree there might be place for control Warlock in future meta, I just say there is none in present meta. Especially for highlander which loses so much just for one card - Zephrys, as Alex is just another way to slow deck down.

Have you experienced any problems with the deck so far? Any matchups it couldn't work against? I'm getting a lot of responses about it, so I'm collecting data. 

Naja, bisher habe ich halt erst 4 Games gemacht - und parallel eine ganze Dose Schinkenwurst gefressen - ... Daher kann ich dir bei der Datenerhebung nicht helfen tun können.

Cool deck. I added DQA for Prize Vendor.
