Except it isn't, since initially the class gets to use elemental carbuncles for its early levels to do the same one-off attacks that the egis will proceed to do. They go in, and then get off my screen. We do not have to look at the ugly egi models for more than 2 seconds, and then we get to use cool looking elemental magic. Then once we have Bahamut he sticks around along with Phoenix during their respective trances. Now at 90 and beyond we will no longer have to look at the egis at all, and certainly not at all during the eventual 90-100 levelling during 7.0, and so on for future expansions.
The foundation they've given us is meant to last far longer than just the expansions of the Hydaelyn and Zodiark era. We will continue growing in strength and gaining new abilities but for now we have the base of some really great things coming in the future during the next 10 years. I would hardly consider that a tiny portion of the game. At the moment we do not have specific details as to whether we can glam the egis into carbuncles but it wouldn't surprise me that they retained this option in game and that it wasn't available in the media tour because they didn't flag the characters as having completed the egi glamour quest (or the quest to even be able to dye gear for that matter).
Again, I implore you to do something more productive with your time than trying to convince those of us who are excited for this rework that we should be sad over the loss of a mechanically and visually unimpressive job in favor of everything some of us have been asking for the past 8 years.
Then what you were looking for was Time Mage or Necromancer, not Summoner. If dark poison magic was your thing then Summoner was not the class to co-opt to fulfill these desires. The point of Summoner is to summon beings for cool looking powerful attacks. Not to be a cheaper version of Affliction Warlock.
We will not miss visually unattractive pets who did not even do what you told them to do whose best attacks hit like wet noodles. It absolutely mattered because the beings we were summoning most of the time were useless.
