So after rejoining the game with the jump potions I noticed I had no seals so I decided to grab titan-egi and go on a magical adventure to fate grind and learn my job's buttons and get enough seals to get the GC rank necessary to turn in dungeon gear for seals.
First off, Enmity generation is on point. If I start off with diversion in a fight and go crazy Titan never loses hate, however that only applies until he inevitably dies. After exploring and moving about I reached the lvl 40+ areas of ARR, and I started going through two or three titan egi's a FATE. Any mob comparable to my level and in a group of more than two were tearing titan apart like tissue paper. Large FATE monsters would eat like three or four titans as well. THe only way I was able to solo FATES past 40 was resummoning at critical HP, Lucid Dreaming, Diversion, Rouse, and spamming Drain to keep myself alive until Titan could take hate. It worked, but I had alot of close calls and my DPS had to completely stop for a long time every about every 2 minutes on a larger enemy FATE (Thank goodness it was two munutes because Titan couldn't tear the monster off me without Lucid and Diversion!) and this issue only seems to get worse as I go higher and higher in FATE levels.
If you don't want to give Summoner a useable Physick, please consider giving sustain back. Without a way to sustain our titan we can't effectively solo stuff. If you for whatever reason you don't want to give us Sustain, then consider adding sustain to Titan's abilities. Possibly under Earthen Ward so that it recovers HP while taking less damage every two minutes. As it stands there's little use to this skill since egi take less damage from AoE and it's really only Auto-Attacks and direct weapnskills/spells killing them.
Please do something because it is hard doing stuff by myself without a working tank.
