Thanks for all the answers, some rather mixed opinions but that was to be expected I suppose.
To clarify, what I'm aiming for is indeed fooling around a bit in 5man heroics, some LFR and perhaps some casual raiding (pickup group or laid-back normal difficulty raiding group if I can find one of those to my liking). There's absolutely no rush though, between all the real-life stuff and work I won't have too much time anyway and once I quit hardcore raiding in early WotLK I've not seen much use in rushing content.
As for resources, level 85 characters I have plenty but I'm probably very low on gold, so crafted items won't be too easy. But again, I don't especially feel the need to hit LFR within a week or whatever (will probably take me longer than that to level something
)
Overall though, as it seems dailies are not 'that' mandatory and the positive replies seem better constructed and argumented I guess I'll just give it a try.
