So with the release of prelim focus costs im noticing that unless our stings (or at least serpent) costs <20 or so dealing with keeping serpent up as close to 100% as we do now becomes very inefficient considering how many times a BM and SV hunter need to cast it during a boss fight. So ive come up with two possible solutions that I would like to throw out.
1) Each spec gets a talent to refresh sting duration
2)Stings become a self ranged weapon enchant (similar to how shaman have their X weapon skills) and proc 100% on next shot with an internal CD equal to what the shots cooldown is. IE Serpent will always proc since it has no CD. Shooting a target that already has it will simply refresh the duration while Viper shot will only proc once every 10 seconds inline with the 10 second CD it has now.
For various reasons I like 2 more but since the code for 1 is already written into chimera shots skill it would be easier to introduce from a codemonkey standpoint.
