And you say I don't understand? I understand completely. If you want to get the best weapons in the game, you have to do stupid retarded stuff.
Look back to ffxi 9 for example. You happily play through the game and as you get to quite a high level, you think "I'll get a guide to see if there's a really good weapon that I can get that I've missed". In said guide, it says that you actually had to NOT open several treasure chests as you progressed through the game. 1 of which was even in the prologue before the main part of the game even started. If you want the uberweapon, you now have to completely restart the game to get it.
You have 2 choices. you can stick with your level 95 weapon, which is superior to all weapons apart from the level 99 versions; or you can do stupidretardedtrial to upgrade to 99. You have a choice. Noone is forcing you do do anything.
Personally I choose not to do them. You may all make your own choices.
The other thing is that people insist on ciomplaining about this content even though it hasn't even been implimented yet.
