@Urist: I suggest you start sprucing up the OP if you want to get more people invested in this game. Give a rundown of the campaign, house rules, player list, system, maptools/D&D version, etc.
Also, can I suggest the following house rule for our more squish members?
Pretty much, we all get the Heroic Durability feat for free-that gives +10 HP, and our first HP roll is always counted as max. One of my former GM's uses this, and we all agreed it was fine.
That really decreases the chance of some monster one shotting the wizard.
