All I'm saying, it's too soon to judge what we have and don't have. Half of your suggestions for example could be a simple part of patch notes that are guaranteed to hit every classes current skills. All they showed in that video in general for all classes was what was being added to the class. Fairly sure they they didn't even comment on how any of the classes current abilities would be changing. Not to mention we also don't know all of the affects of the new abilities and/or traits being added. Several things may very well change for the better but meanwhile everyone is going bananas now when we don't even know everything and even if this was everything, we still again don't know how much this changes the balance of power.
The Pets, perhaps a promise broken for now with the new Egis, but I refuse to believe the correct idea was to add more Pets when the current system has incredible flaws that need adjusting. Before we add more Pets let's fix the current issues we have with the ones available, after which we then fix the problem of the go-to pet. No one is saying more Egi's wont come just not at this time. Even if more didn't come, it's not a terrible idea to think that maybe just maybe they can expand on what we currently have ability wise of Pets and this may actually become a interactive class + SMN abilities.
Let's get rid of what everyone's ideal version of the FFXIV Summoner should be, because everyone is thinking differently there. Instead work on what we currently have and strengthen some of the current aspects of the class that are lacking. For now, I think they took one thing into consideration of SMN in 3.0. The cooldown period you have every 30 seconds until you get another set of Aetherflow stacks, which is big because that's where the main loss of DPS comes from. Their answer to that is Bahamut Trance which to me feels like an interesting new way of connecting summoners to the summons / primals. They could further expand on this side later on as an option while also working on new egis to become a summoner / evoker (channeler) combo. Who knows what else they could do. Another rather common complaint about SMN was that it was boring to look at when playing because it didn't have many flashy abilities at all so people weren't enticed by it. Two birds with one stone with this Trance ability. One step at a time I say.
The biggest thing I want from the class, is perhaps to streamline it alil. It's a very complex class to grasp and imo, too complex. The hardest part of it is maximization and many SMNs currently aren't capable of doing that because to me, it doesn't articulate well everything you need to do to get there. Just too much work to play the class correctly, and that to me, needs to be worked on the most. If anything I'm surprised people aren't up in arms that they may in fact be making it more complex with some of the current stuff we know being added. If people can't easily decipher how to play the class correctly, then to me that's just leading to further people abandoning the class because it's seeming more and more incapable of doing well when people consistently pull bad numbers but then you have a slightly simpler system in BLM.
