Pretty well.  We didn't do a whole lot of combat last session, but we're currently running with a broader spectrum of ACs against the newly buffed enemies, and sort of ran into a problem with the AC range.

Clothies are too damn squishy, especially priests.  They really kind of get shafted compared to the other classes as they don't start off with the armor buff like Mage and Warlock do.  Our priest died fast once the quillboar got on him.  It was like D&D Wizards all over again.

By contrast, the Warrior was just too damn high.  At the level he's at right now, he's got 20 AC, 25 in Defensive Stance, which basically makes him invulnerable to damage from equal mobs. And he's only in Mail.

So AC values are going to be adjusted towards the center on both ends I think, and I need to shuffle the priest abilities around so they can maybe get Inner Fire at a lower level.  I may also reign in the Agi bonus a bit, adopting something akin to the 3e "Max Dex Bonus" mechanic.  

The new test crit system worked out well though, players actually crit now, which wasn't really happening before.  Now I just want to figure out how to link the crit ranges to stat instead of weapon, though this sort of removes one of the very few points of weapon differentiation if I do so.  I've also considered adding something like LOTRO's weapon abilities, where each type of weapon has a certain base minor bonus, so they're not so generic.  

We're too low level yet, so we haven't gotten to it in play yet, but based on some chargen tests I do foresee we could have some problems at high level with weapons being all but useless compared to character abilities, thanks to how many of them scale directly with level.  A lvl10 Warrior deals weapon damage + 10d6 on a Heroic Strike, which is so much damage that stats and base damage start to become meaningless, especially since base attributes, even with magic gear, don't escalate quite so quickly.  We'll see, that's all theoretical at this point.

I am a big fan of weapon differentiation.   I just submitted a whole article on it to Knockspell for Swords & Wizardry.  

Attaching a Max Agil Bonus to Armor is fine.   Or, you could give a -X Agil bonus for those in armor, thus emphasizing Low Armor Missile guy versus Heavy Armor Melee guy.

Is the new test crit system in the current PDF?  

As for weapons being useless at high levels, I am cool with grand heroes being able to decapitate people with a rusty dagger.  But I do understand that you want magic items to be worthwhile and desireable at 8th and beyond.

THe new crit system is in the Alpha 2 version, yes.  Basically I switched to a D&D3e style die range.  

There's a part of my that's still not sure if a crit mechanic is necessary though, as the carryover mechanic does often do the job of giving bonus damage on really good rolls.  Our first playtest actually ran without a crit system, because the die mechanic didn't work well with Magicstar's die roller (neither does the new one, sadly), and it seemed to play out alright anyway, plenty of bonus damage was flying around without it on good hits.  

And like I said on the high-level issue, still don't know if it'll be an issue in actual play, but it is something I'll be keeping my eye on.

Any actual play reports?

No reports or write-ups online at this juncture, and I'm not sure any will be coming any time soon.  I've never been big on AP reports, writing them is tedious, and reading them moreso.  I have been trying to update the errata on the wiki and post on any highlights in the game threads on CoG.

Further, the atmosphere here isn't really what I signed on for anymore, so I won't be checking this forum in the future.  Future discussion of the game will take place on Colony of Gamers' analog gaming forum, where the playtests have been taking place, and of course the Drums of War wiki.

I welcome you to bring any further questions there.
