Maybe learn to pace yourself and it won't be exhausting. TC mentioned they spent seven hours trying to get Bahamut. Take a break. Try a few matches more later. Pace yourself. This is an MMO, things can and will take time. Triple Triad hasn't even been out for a week and people are whining they can't get all the cards.
Like other people have stated, these are all optional items. This game has many things that are a grind, like the relic quest (but nowhere near close to other MMOs), as well as a HUGE number of things that are handed to you. Stop seeing gear or cards or any other reward that you MIGHT get as the determining factor for how much progress you've made during your play session. Do x content because you want to, if the item you desire drops, that's great, if not, do it again now, or maybe tomorrow, or the next day. You'll get there when you get there.
Stop thinking you'll get everything handed to you. Take things at a comfortable pace and you won't burn yourself out by trying to get a card, relic, mount, or whatever at a speed that is unhealthy for you. Enjoy the journey more than the destination and you'll have a lot more fun.
Someone mentioned 2.0 earlier and said how great it was. Are the rose-tinted goggles already being distributed? Are we talking about the same 2.0? The one where people repeated TWO dungeons every week to cap tomes and a lot of people wouldn't even touch Coil because the rewards weren't worth the effort to them, and the ones that did only logged in on Monday nights to clear their turns and log off for the rest of the week because there was absolutely NOTHING else to do? The 2.0 where there was absolutely no open world content and the best armor was obtained by repeating WP again and again?
