Kheldul's equipped item level is 527. Everything is at 522 or better with one exception. The ranged weapon slot. That slot has the gun from Terrace. Sure it has a +500 sha agility gem and it's been upgraded since the day I got it. But it's only an i504.
We've started doing heroics. I'm still often the highest DPS, but the ranged slot is so incredibly important that it will soon gimp me.
I do have the LFR bow. These are supposed to be better. With the extra gem, bumping its ilevel up twice, and reforging I don't get it more than less than 300dps better out of 150K+.
I did a fair number of heroic scenarios and won what I thought would be a great base i516 gun. Awesome. Except the sim craft and femaledwarf both say it is worse than my current gun. There are two problems with it. First it can't get a gem slot as it's not "sha-touched" nor does it come from the "Throne of Thunder"! The second and bigger problem is that it's speed is 2.70. There aren't any other even semi-modern ranged weapons out there that are that fast. It evidently makes a big difference.
What makes this hurt more? My current gun was something it took me a LONG time to get. I've been through this all just before. Far more boss kills than anyone would expect. I'm experiencing the same thing now. We have had a ranged weapon drop ONCE. The other hunter got it. Since then there has been nothing in raid.
Coins you say? Well, the other hunter has gotten the zone-drop 522, the iron qon gun, and -- I think -- tortos' bow from coins. I don't have a strong memory of that bow as I think I made myself forget. I only use my coins on the three bosses that have a ranged weapon in their loot table -- to increase my chance to get a coin drop from them. Unfortunately, I've seen five pairs of shoes from Tortos. He'd even love to give me one, but of course that's not possible. I'd love to take one too, since I'd like our first heroic and/or thunderforged drop to be a roll-off instead of a QQ party for all.
Overall, I've got 79 10-man ToT boss kills under my belt. 11 weeks of 3 coins for 33 coin rolls. Clearly, I get loot. But I have to wonder if the drop rates for these ranged weapons are too low. wowhead puts them at 0.1%, 6%, 9%, and 10% each. The loot tables are huge. Do other people have similar issues? And why the hell have I won five pairs of Quakestompers? I'm going to have to try and throw them at the bosses.
