Hihi
So you wanna hear feedback about people opinions about the three specs.
Here is mine. And i want to hard underline i don't want to offend anybody. However if you ... well im saying it again i dont mind to offend anyone.
Fire spec - easiest of the specs and this is the "inner warrior" in the mage. It basically revolve into 'mashing buttons and spamming Pyros. Best described as lunatic jumping around and mindlessly spamming in the style "BUUURRNNN! BURRNNN!!! MUAHAHAHA!!!". Not much thoughts involved into it, just reaction based spec, maybe only when the time to use Combustion come and you want to use it to its potential you have to use your brain better. :}
Frost spec - to me this is the spec for the "average Joe". It requer a bit higher skill cap than fire.
Arcane spec (this is the place where i promote my favorite spec
) - to me this is the spec that yells "I am mage!". It requer a bit higher IQ and skill cap to be used to its potential. Also you have to manage a lot of things - your precious mana, positioning, your cooldowns(all of them) and very very deep knowledge of the fight so you can predict to higher degree the RNG during the fight so you can optimase the damage you can potentially do during the encounter.
It is the most hardest to learn and mistakes are punished severely.
