Are you kidding me?

25 plat is perfectly fair for a single-use ticket that grants direct access to the boss map of the brand new campaign. Be glad it is not 35 plat, which is what Maxx Cave used to cost during the first half of the 105 campaign. It was later reduced to 25 plat, and now that it is not the current campaign, the price has dropped to 20 plat.

maxx cave dropped 200-300k worth of experience orbs per run and bosses had a fair chance of dropping elite gear.

you're lucky to drop a 2-5k xp orb and receive a trash drop after grinding ebonthrax for 5 minutes straight.
