This post is in regards to raiding in general (Crystal Tower, Coil, etc.). I believe that some of the community's troubles with content is that the raids are either rendered too easy over time (natural ilevel increase, echo), or are way too difficult for casual/semi hardcore players (Turn 5+, Titan EX).
A possible solution for raiding (in the expansion obviously) would be to create much larger raids with far more bosses in them (like 10-15), and with the raid starting at a much easier difficulty level and increasing towards the end. This would serve 2 purposes: 1 is to allow a sense of progression within a raid, and 2 is to distribute some of the gear in a better way (cause honestly right now the loot tables are way too large and only having 2 drops per turn per week makes it a bit of a stretch, especially for people that are new to clearing turn 5 now and haven't been doing Second Coil for months already).
Many of the current coil bosses could have their mechanics pared down and used for other bosses, some of the phase transitions and amounts of phases per fight is completely unnecessary and doesn't really add to the fight. Twintania's final phase for example could have been used for some other boss which would focus on moving out of fire and not covering the entire arena in flames (and the flames could be far more deadly), instead of just having it tacked on as a breather for having beat twister phase.
In my opinion the Leviathan Extreme fight was perfectly tuned with one main mechanic (the divebombs and boat slamming), and then a dps race mechanic (spumes), and then a control mechanic for tanks (adds). It challenged everyone without being completely overwhelming with phases.
SE has proven they know how to make good encounters, and over the years they have made bosses with fun and memorable mechanics in previous games.
What do you guys think?
