I"m not a playtester, so here's my feedback on what was compiled so far. (Thanks GX.Sigma)
1. Skills aren't mandatory IIRC, right?
2. Wizards aren't proficient in javelins normally (much less flaming). Just go ahead and give them "every wizard gets their own custom Magic Missile." I've used ice knives.
3. Mage Armor as default makes me think Wizards are supposed to be in melee.
4. Give the Fighter EVERY Fighting Style listed. Missile, sword & board, two handed, shield wall, whatever. All of that stuff is the complexity and awesomeness of an elite trained warrior. Let 'em play with it rather than "Every one is specialized" and sucks at everything else. Specialization should be custom by the player. "I call this Stabbing Fist School"
(Thanks for the spells where we get duration, some oomph in power, and "oh no!" temporary control loss again.)
5. Variable donning armor time? I guess I can see this for the plate mailers. Does this mean we're talking 1 minute Rounds again? Interesting.
6. "Monsters without Ability Scores", he says. Tons of stuff has ability scores. Rolling these for monsters only as they are needed is a nice touch. Just as that last point on rolling HD for every monster during prep.
-- However, here's the catch with making Ability Scores Saving Throws. Now we really do need to know what they are for every single monster encountered. That single Monster S.T. Matrix looks mighty fine now, huh? My only suggestion for breaking out of this is making A.S. S.T.s PC-only.
6a. Whoops, he says "can lack ability scores". My fault, but I'm leaving it as both points above may still apply. No problem with no A.S.
7. 20 status conditions is not that bad. These are the physical results of different effects (combat, magic, miracles, whatever). But I really think the 3 Fear effects are unnecessary. Isn't this making combat an attrition early decided and long to resolve? (e.g. HP doesn't affect "to hit" ability for a reason)
8. Action economies are needed, but I highly doubt you'll go my way on this. (maybe you're making these optional?) 1st off I go by monster/race. 2nd I include any and every time length but zero (e.g. round, turn, etc.) 3rd these are all unknown and behind the screen on purpose.
9. It was funny to hear early D&D monster creation called 4e, but bad because it might actually be thought of as representing monster traits in the game world. (go figure)
-- FYI, you might want to add a default 1st time monster meeting method instead of naming them outright. Relay all sensed traits available to the PCs and let the players name the "thick red haired humanoids with tusks and porcine snouts". Pigmen is a fine name, even after they learn the creatures call themselves orcs.
10. Lastly, HoOrah! for cursed items.
(Thanks for keeping use afloat and keep up the good work)
