No, it's not trolling. The posters who disagree with pointless melee buffs, and embrace RDM's oustanding magical capabilities, are people who have well-geared RDMs and who enjoy playing RDM. In any case, we'd be well within our right to post here even if we didn't have RDM leveled. It's not 2002 - smart players don't need to level every job to gain a deep understanding of gameplay mechanics.
Furthermore, you're vastly overstating your melee complains as a 'community misconception'. No, it's an Alla RDM Forum misconception. Everyone else in the overall community, forum posters or not, recognize that RDM enjoyed its status an exceptionally powerful mage over the years - so powerful that even SE hesitated to tweak it much as the level cap rose past 75 (and even nerfed Saboteur). And as much as you and the melee crowd may hate it, SE's vision for RDM as revealed in the Manifesto is, in general, the correct path for RDM.
Meleeing on RDM as a hobby (or against weak content) is perfectly fine - meleeing as the focus for RDM is not fine. If SE focused solely on RDM's melee 'talents', it would bring about decimation on par with the Big RNG Nerf.
