With dual spec now having been around for a while and us probably being well on our way to get tri-spec or triple spec further down the line (call it prophecy if you will) there's pretty widespread yet seemingly minor changes to adapt to the option.
Most guilds seem to have undergone a short period of loot rule adjustment to deal with the whole main-spec / off-spec concept of dual speccing.
There were some pros and cons listed here and there about dual speccing but in the end most have settled on a main-spec / off-spec / not-specced concept and built their loot rules around that.
I had expected more really: guilds forcing all the classes with healer capacity into a a dual specced healer role, refusals to spec your second spec for the guild resulting in widespread drama, hefty complaints by pure dps classes that really only have another dps spec to spec into.
None of these seem to have materialized. The cost of dual spec is not prohibitive enough to assume people don't have dual spec yet at 80 and so it almost seems like dual spec was introduced and absorbed wholely by the wow community at large without too much fuss.
Bummer really... nothing like a broken system to bring all the classes closer together and end some age old class rivalries (or at least put a damper on them for a while). Although I suppose it's probably wrong to wish doom and gloom upon the system just to have something amusing to blog about (or is it?).
Personally my dual speccing adventures usually ended up with me having my usual spec as main spec and the dual spec is usually relegated to being a 'test area' where I throw fairly random stuff together to see what it does. Oddly enough my re-speccing cost have gone up significantly since dual specs were introduced because now I am in a perpetual state of having 2 specs I am not entirely happy with.
I still consider carrying extra sets of gear largely a waste and my dual specs tend to feed off of what is already equipped... but in the end my primary problem with dual specs is not the concept but the fact that I always forget I have it.
There's nothing like standing at a meeting stone waiting for that healer to arrive to fill up your party and not remembering that your moonkin is also a tree... or alternatively when I do remember repressing the thought that I might as well heal the thing and get it over with rather than standing around like a stupid dps waiting for a healer (because I don't feel like healing at that time).
That said, now that we have dual specs and no obvious problems (obvious as in even I noticed) have arised I have a feeling we'll soon be looking at tri-spec at the cost of 2k gold.
Maybe dual spec was just an elaborate gold-sink after all. So then dear blog connoiseur: How did dual spec impact your gameplay?
