As a healer cleric who can't even cast regenerate on my Summons anymore...
My summons are straight up garbage post Sequencer updates.
Congratulations to all the arcane classes that can bypass the "Your not allow to buff your summons" through mass wardings.
I don't have those, and I don't get to stack them ontop of sequencers, so guess what? My summons suck, and require immense amounts of baby sitting to get through every encounter they ever get into. If I wasn't given infinite cure moderate wounds stacking it at auto empowered and auto maximized then they'd die to a standard bad spawn. (And they still do manage to die all the time from being turned, from being just bursted down due to having no SR and low AC, or just being outright dismissed because random banishment spell just deletes them, so much fun)
I'm sure Warlocks running around spamming massive AoE spells mass summoning mobs and never running out of any offensive options don't run into many problems (Most of you are rocking undead, no conduits, and get to get mass warding and standard AOE undead buffs, and can repeatedly summon them! Not just a once a day thing, some warlocks don't even sequence their mobs because they can just STRAIGHT UP BUFF THEIR UNDEAD AS IF NOTHING CHANGED AND DON'T NEED TO CARE, MUST BE NICE). I'm sure wizards whom can sequencer their summons then mass buff them to make them even more powerful are finding tons of success with summons because they are bypassing the rules that everyone else has to follow.
Me as a healer cleric? Neat, I get to cast bless (You know, the rounds per level spell now) after using a sequencer! I can't even cast regenerate on my summons, so I'm either stuck taking domains that make zero sense (I thought giving clerics the haste spell was so they didn't get shoe horned into taking specific domains to be remotely optimal?) to get what? maybe Two mass zoo buffs? Or I get to just only be stuck using sequencers and having no other buffs I am able to cast on my summons because all of my buffs are single target except bless and prayer.
I also now have to choose between a Druidic Sequencer if I want a semi-defensive option with some damage, a Arcane Sequencer if I am needing concealment, or a divine one, if I'm worried about them being dismissed! but guess what? other classes basically get the effects of Two at any time, because they can just cover the buffs that are missing through mass wards! They don't need druidic sequencers for Str Dex and such, they just mass ward and then pick between Concealment or Spell resistance. how nice for them.

(Undead also still getting all their specific undead buffs ontop of being mass wardable, AND sequenced is also super fun with all those ridiculous new streams and buffed mobs)
But sure, nerf the summons again because SOME classes can still make them stupidly broken (Again because they get to ignore the rules that everyone else is forced to abide by), lets just ignore the fact that if you just made it sequencers or nothing and made everything the same you'd find a drastic drop in usability and power summons had for various classes.
The power summons have are NOT static across the board, because certain classes were given access to tools that bypass the rules everyone else has to abide by, which is absolutely stupid.
This entire post sequencer update has been BLATANTLY imbalanced, and now everyone's scrambling and demanding summons to be nerfed AGAIN, despite the fact it's not going to effect everyone evenly, and I think that's absolutely ridiculous.
