Garuda/Titan/Ifrit EX and Coil T1-5 are not "end game" anymore. They are buffed so people can get to the current end game, and even then there are substantial roadblocks. Even with echo, Titan EX is still hard. Even with echo, Twin will make you cry. When you say stuff like this, people who actually care about progression are raising their eyebrow at you because they've been done with these fights for ages and are actually playing through the end game content of the game.
