ilevel requirement for titan HM was stated at 70, and crystal tower is i level 55 to enter, with i80 gear rewards.
Is this what they said? Because this doesnt make sense. Wanderer palace gear to get ilvl 80 gear but titan requires full darklight and a garuda weapon? Im thinking you have this backwards.
That's what they stated and it makes perfect sense.
i70 is Darklight/Darksteel/whathaveyou and a Garuda weapon/crafted equivalent. That's easily obtainable even if it takes time.
The reason for the i55 requirement for Crystal Tower is smart. It's a 'casual' raid and allows people to experience raids in a more laid back environment on their own time and in not as demanding an environment as Coil can be a times. Needing only pieces from WP/AK/PS/CM/HM, and possibly some Darklight as you get tomes, allows players to slowly gear up for their Relic/HM Primals but still do *some* large group endgame content so they're not spending forever grinding just to get there.
Secondly, HM Titan is still needed to get through a relic's story and completion and it's required to even enter Coil. By having Crystal Tower drop i80 gear, Mythology giving i90 gear, but Titan requiring i70 gear gives people multiple avenues to meet a really small requirement. When you're getting i80 gear from a place that you can, apparently, run as long as you like and fill missing slots with i70 crafted and/or tokened gear it's easier to reach that requirement to get into Titan.
Remember, CT's gear level is to make entrance into Coil easier for newer groups that haven't gotten in yet. Titan isn't exactly the most difficult content in the game, but it's a major step up from HM Garuda in terms of execution and numbers needed. CT having i80 just makes meeting the entrance 'requirement' for him that much easier.
