No, I wouldn't, because I honestly can't trust WotC to not change the conditions or pull out the plug from one day to the next. They've done it far too many times now (d20 license, OGL/GSL, Dungeon/Dragon, Ravenloft, HackMaster, Drivethru/RPGnow, Virtual Gametable, free or nominal-fee pdfs with dead tree version purchases...) to trust their "good will" anymore.
That's what might convince me to subscribe.If they mean consolidate all the information into something like the D&DI compendium and build all their rules for each edition into Rules Compendiums (and I do mean rules, not just character options), then hell yes.
This.No.
It's a trust issue. How can anybody in their right mind trust WotC any more?
