To Roll or Not-to-Roll

There's a little uncomfortableness in the raiding guildies at the moment, about the number of drops people are getting.
People seem a little unhappy with the way the loot is being distributed. The intention was, originally, to keep it as fair as possible. Anyone who is in the raid, with their main, may roll on any drop that is an upgrade for their main-spec.

If there are no takers, then it is offered to roll for off-specs, if nobody wants it after that it gets DE'd for shards in the guild bank.

If a BoE item drops, then the same rules apply, but instead of DE'ing it at the end, it gets put on the AH, and the raiders that night split the cash from the sale.

This seems a pretty straightforward system. And it doesn't favour the more hard-core raiders over the newbies, as everyone gets an equal chance to roll.
Sure, this might mean that someone who is new to the raid, or has sketchy attendance, gets a major upgrade, meaning that someone who has been loyally raiding every week, misses out. But I don't see any fairer, and as uncomplicated, way of distributing it.

Buty people are unhappy... So would it be fairer to bring in a DKP system (Dragon Kill Points)?

My understanding of DKP is this:

Every raider who is present at a boss-kill gets points awarded. When a drop appears, that they want, they use those points to bid for the item. The points roll-over in to all future raids, so people can build up a larger number of points.
This means that regular raiders obviously have more points, and have more bargaining power, and newer raiders have fewer points and so less chance of winning an item.
But this also means that people are more likely to pass on a minor upgrade, with the intention of saving their points to bid for that special drop that they want.

In some ways this seems even fairer than the system that we use now. And new raiders aren't going to miss out on every drop simply because they don't have any bidding power, as the more experienced raiders will either already have the item, or will be saving their points, and so will pass on the item anyway.

I know there's addons to help with the DKP systems, but having never used one, or been in a guild with a DKP system, I'm not sure how much work it would be to manage one. Or whether it would be worth the hassle.

Unfortunately for me, it wouldn't help much, as my main competition for drops is the only rogue in the team, who happens to be the raid leader, and so will always have more DKP's than me. But I'm not worried about that. Besides, his DPS could do with the upgrade more than mine ;P

Everyone's a Crit-ic

Apolgies for the delay between my posts again, but I'm sure the world isn't going to come to a standstill just because I stop babbling on.
Things at work are going to get a little more back to normal from this week, so my frequency of posts should go back up too.

Anyway.... Crit vs AP... Discuss.

My DPS is usually at the top of the meters for an overall run, but that doesn't necesarily mean that I do the most damage on bosses. Particularly on ones like Heigan, where I can't even send in my pet.
But generally speaking I'm happy with the amount of damage that I'm doing.
My question is, how do I do more?

At first I was stacking as much AP as possible, and it was working, I saw a steady increase in my DPS. Until I reached 4k AP unbuffed. At that point, my DPS seemed to level out a bit, and even when buffed up to 6k+, I didn't necessarily notice the major improvements that I would have expected.

So I switched out as many gems as I could for +Crit instead of +AP. Which now gives me just under 4k AP (Unbuffed), and about 28% Crit (Unbuffed).
Lookign at my last ReCount meter from Naxx, it shows I averaged 36% overall Crit, and yes I was 1 Million dmg above 2nd place (overall), but my DPS hasn't really moved at all.

I've also picked up t7 Gloves and Chest, so my pet is now 5% dmg higher (which should equate to about 50DPS)
Although I'm still stuck with my Blue helm and shoulders, and both rings, and 1 blue trinket. Unfortunately, the only place I can pick up decent upgrades for all of them is Raids, and my luck on drops hasn't been too good.

So, any ideas? Should I be stacking Crit, or should I go back to raw Attack Power?
