Been running Ridorana Lighthouse the whole week and...

I do get where you are coming form

You keep saying that but you don't.

you want role priority due to the fact that you took the time to queue up as that role and you should be granted some level of safety against other players snagging what could potential be an upgrade?

My personal reasoning for wanting role priority is so I can help my raid team. If my gear gets better then the team has increased chance of killing the boss. Sure something might be a minor upgrade for me, but if several individuals get minor upgrades then the team as a whole gets a big upgrade. This reasoning is actually standard across most raiding teams.

but would that slight upgrade provide such a huge boon to the groups effectiveness that it should granted priority over everyone else in the group?

You don't get where I'm coming from because you don't look at the bigger picture. You keep going on about how the upgrade won't affect the alliance raid's performance, but you don't even think about how that upgrade might affect other content.
