This is a Relic we are talking about here. Not a pet snurble. You can't just take the concept of one weapon and complain complain complain until you get your way. Some things in this game have to be difficult to achieve to retain any semblance of long term goals. Beleive it or not, having some things that is going to take you a long time to achieve regardless of the reasons is actually healthy for the game.

Next I'm going to hear you wanting a guarantee that you beat Ifrit Extreme in your first five tries.

Please, research your means before you start complaining. If you're after a relic you could always spirit bond items for gil or for the Meterial you need. Raw items are cheaply made and sold and can wind up being quite profitable to spirit bind and convert.

Alternatively if you don't want to be a crafter, there are multiple places in which you can farm for cash-cow monsters.

The Double Melded class specific weapons are not nearly the barrier you're trying to play them out to be. Save up, or find yourself a crafter and go for it yourself. Relics are designed to challenge a player at multiple aspects of the game, to achieve a weapon that is supposed to be superior to all others. Work for what you get.

And if you don't, then go for one of the many, many alternatives that are in the game now, or are coming from Skirmish.
