Stop killing characters!
This is driving me nuts. Few things irk me more than seeing a character I've enjoyed for 15+ years killed at the whim of some fly-by-night writer trying to move a few issues or push whatever crappy event they have going now. It feels cheap, rushed, and generally puts their backs against the wall when they fail to develop a new character people care about to take their place and end up having to revive the deceased later. Worst of all it generally happens with little fanfare and does nothing to truly promote whatever pet project they are pushing that week. Eddie Brock commits suicide on a off panel. Sabretooth gets decapitate in the snow. Thanos has his heart ripped out. Absorbing Man and Carnage are crushed in space. Mr Sinister gets overpowered by Mystique. Punisher gets sliced into a dozen pieces. Now they feed Taskmaster to Rulk as a afterthought. Hasn't the Hulk family ruined enough characters since WWH? So they break their "dead means dead" policy and bring them all back through plot holes, or in some cases without explanation at all. Yes its not a recent development, but writers in the 70s-90s at least seemed to respect, if not love their creations and characters. Now they are just using them to get a very marginal pop in sales that weakens them as a whole.
