I have a character on gywdion that's a lvl 129 rogue but latly I don't want to be a rogue I want to go full Mage but idk because I need rogue to farm so I'm stuck in a pickle please help

From personal experience I would suggest getting that rogue higher beforehand. My primary and only class that i play is mage. It is very costly, even the cheaper routes are pretty pricey for new-ish players.
I only have 4o energy sigils and it does really hurt my gold as energy lixes are still not enough to solo lix with thus i must still use res pots. As for the farming issue, mages are still pretty good for that too.
My experience is that energy consumption is bearable until level 160-165 (even that is pushing it) and i can only imagine it getting worse. For energy lixs to be most effective one must have alot of energy as it restores %en. Thus making it difficult to poor points in vitality and in turn it would be the best option to use eshield. If you can not afford some nice lux or gear that adds focus / vitality mage class would be very difficult. Mage is arguably the hardest class to pick up as a first class, but it does have its rewards too.
Its all a matter of what your status is ingame rather than a right or wrong answer. If you are in a clan that can gear you with top tier items right of the bat then go for it dude, however if you'd struggle to get meteor and frozen and DL then i'd wait it out. Patience is key for mages, if you lack patience then give making a mage a miss.
Energy consumption is not the only hard thing to deal with as a mage, the armour value of gear is low...as is for druids...Rendering mages open for big autos and skill hits. I truly take my hat off to anyone whom has mained a mage and stuck through with it.
P.S. from my experiences, i might be doing something wrong because I spend more time dead than alive when levelling in aoe mobs
