I have a bone to pick about echo
I've been trying Garuda Extreme for a few weeks. It's not easy, and you need to know the fight to be successful. Now that echo is out, you can get a little edge for groups that are less than perfect. That's pretty excellent, except I'm sick and tired of people finally getting to 20% or 25% echo and bailing. If people know the fight but make a mistake here or there, 20% echo is an amazing edge up to finally finish this fight.
If you're not willing to stick it out and finish with a group that knows the fight but isn't perfect, don't join.
I am not perfect, and I'm not expecting anyone to be perfect at a fight. If you join up with people, stick it out with this new echo feature and give it a shot. If it still isn't successful, don't worry you can move on and waste your time farming level 10 fates...
