That's probably the easiest way out if you want to spam endgame dungeons 24/7 for profit. You can also use tokens that you get for helping rookies to replenish it and right now wintera has a chance to drop those tokens too.
There are also many side activities that don't require coins to play and pvp, but probably not what you look forward to as a pve priest in case you're going for that approach.
Pvp is fine too. I just don't play mmorpgs to go solo, there's singleplayer games 4 that. Leveling up is already a chore like alwaysss.
