I think the changes fit Perfectly. Before there was no incentive to do Titan except for your relic quest as the weapons were equal to Garudas.

Then is Allagan, I'm sorry to say that Turn 5 is the hardest content of the game now, and as such it is perfectly logical that by clearing it you should get the best weapon in the game. If not, what incentive would have people to do it?. And dont forget that as the most difficult drop in the game a ilvl 90 weapon is almost mandatory, so you need your relic +1 for clearing T5.

Then there is Primals Extreme that also drop ilevel 90 weapons, well for me having a variety of choices is allways good. Those weapons allow you to spend your myth on other gear slots and get good weapons for your alts.
