I would have to agree with buffing the Dragon Fang tokens but only up to 5 tokens max, an elixir for increase chance to get more is a good idea too. Also STS should add tokens on weekly quests rewards too.
Haven't farmed that much myself but the new gears drop rate looks fine based on CS listings. If the devs decided to increase it more I'm afraid after like 3months or so, no one would runs in the new campaign again after obtaining the new gears. We need more rare loots, its time to make the best weapons, vanities and pets lootable in the new campaign for everyone instead on the limited timed events.
