Changing the job does not mean it would make it worthless, unwanted, or useless in any way, change is the foundation upon which jobs and the game grows and evolves. RDM has not evolved since it's redesign but the game drastically has, and the way I see it is the game is not going to change to cater to us. Now we can stick to our old ToAU mentalities with the way we were pigeonholed into such a drolled out position, but the fact remains we're not wanted for what we can do as it is, meaning all we really can do is change to become better and find that new niche we will be desired for.
With change all aspects of the job will have to be taken into consideration because RDM has alot of growth potential, it does not mean it has to be a melee change, doesn't mean it has to be a mage change either, for all we know SE might actually make an intermingled change combining aspects of both in a way similar to some BLU spells are tied into physical acc.
However, It's the fact people don't want any form of change, is exactly what stifles the growth and keeps RDM from getting out of the hole it's in.
