I would say that they aren't worth anything. They are both missing important mods, namely higher ias, edmg, and sockets. Of course, a rep mod would be great for the first claw as well. Skills would also be a factor -- namely venom, mind blast, and/or lightning sentry.
Since the war fist claw line is the slowest claw in the game at 10WSM, it's not very sought after. I'd say a 40% ias is almost a necessity on them just because of how slow they are. (Although I guess you /can/ wsm bug them, but still.)
We're also very late in the season -- pvpers will want higher end claws instead of low ended mods considering it'll be bumped into NL soon and NL has a ton of items to offer for those that are interested in that.
For instance, I tried to sell this claw: http://img687.imageshack.us/img687/8209/clawc.png at the beginning of the season. Like... around November - December. I couldn't even sell it for an ohm, which is equate to around 1.5 hrs right now. Highest offer I got for it was an ist since my claw is viewed as a 'temporary claw', and this was back when people were actually seeking these types of items.
Ah okay, I don't really know which rares to keep, but I've sold similar claws like this for cheap like Ists and stuff. Perhaps you're right that people just want them as negligibly affordable claws to use as temps.
Which claws are worth keeping? The non-Scissor Suwayyah types and the talons? IAS, ED, Fools, Staff Mods? So if any claw is missing either stat it becomes pretty much worthles yes?
Then again, I sold a Suwayyah with Fool's, 1os, 30ias, 150% ED, ~5% LL and 8 Str earlier this season for 1 HR lol zzz. Only had +1 Dragon Flight for staff mods though.
The most sought for claws are Greater/Runic Talons, although the claw counterpart works as well; sacrificing 10wsm for lower requirements. (by like 3 str and dex.) These are the most popular claws because of their speed.
Yeah, claws that have at minimum ias, ed (I say 250+) and fools mods. While you may be able to get some worth out of lower ed, it may prove difficult to find the right buyer. Of course, it's easier to get a buyer with the right claw, as well. With 2os mod, your worth gets increased by a ton. Staffmods are always welcome and will increase the value of it as well.
Of course, it depends on the buyer and the like, but that's probably what you're going to be looking for as far as rare claws go.
