Here are a few things that could be implemented that wouldn't make smn over powered

BP- Timer reduction. I belive the hard cap should be set to 30-45 seconds putting our ability to DD and buff above average but not outshine the main buffers/DD's
Why?

Current gear allows for -29 seconds off bloodpacts and a properly geared summoner can crank out 4k+ damage BP's with no hate on the SMN aside from JA use which is negligible. Giving 30-45 seconds would make it spammable for a fraction of the mp of a BLM with no hate?

We already have god mode its called brew.

If not lower the BP time then introduce more gear that gives - delay time. Gear giving BP Delay - would be amazing since you would still have to work for it. And would help with what i said above.
Yea its called working for what already exists.

-2 SMN AF2 Legs
-2 SMN AF2 Feet
-2 SMN AF2 Hands
-5 YYRobe
-4 Accord Hat
-1 Caller's Earring
-3 Tiresias' Cape
-10 Magian Staff of element choice

Thats a total of -29 seconds and this isn't counting any additional -BP gear in the 90-99 stretch. I think it's fine.

Make our wards stronger and duriations longer. Many of our wards have gotten obsolete. I think maybe by making our wards behave such as avatars favor as far as avatar favor is calculated by summoning skill. For instance blinkga no one really needs it, if you want shadows just /nin maybe have this job ability stack with utsu? There are many other abilities but i am not going to go over them. Alot of the buffs still reflect the lvls they were earned and need a solid update.
Summoning magic already affects buff duration. Hastega has a 5 minute duration(2 min longer) if you have enough summoning magic. Earthen Ward could use some tweaking to be based on skill and not levelx2+50 which is a static 230 at 90 which is laughable. I do agree something need an update but even if it was updated would you use Ice Spikes or Enthunder wards? Probably not. Also blink is fine.

I dont know if this method would work but I think it would be awesome
1.Path: Rage= Blood Pact delay - all summons gain a damage bonus to blood pact: rage also gains bonus in ACC,ATT,MAB, and MACC to avatar while Path:Rage is in effect blood pact: ward is weakened and Blood Pact: ward delay is +
2.Path: Ward= All buffs from blood pact: wards are enchanced, duriation, potency and area of effect are enchanced. More could be added to this i am just not sure what i will leave the ??? to you guys. And same thing Rage is weakened and delay is +.
It's an idea but I doubt it will happen. SMN is more of a heavy DD with some support, your suggestions is turning it into a support role and to be honest we all do enough healing on SMN to not be burdened to do it more. Also avatars already receive a bonus to BP:Rage through TP affecting their damage along with merits giving 40tp per merit bonus and the pants granting an additional 100tp for damage calculations.

Adding additonal pets such as healing pets. I would love to see a new healing pet so that way we could have a substitute in a bad situation. Say the whm dies well then the smns can rip out a healing pet. But make this pet diffrent from the other with lessened BP times and just a whole new set of rules to keep a party/ alliance alive.
This isn't necessary(see comment about SMN being a DD above) as that isn't our role. What should be done though is learning how to properly control a Light Spirit. It is possible to get the recast time for spells down to 13 seconds per helpful spell which is pretty good if you ask me and if used properly can be more helpful then waiting on BP timers and needing MP.

I would love to see more suggestions from other users. SE watchs these forums so if we can throw out ideas they may incorporate them
Well I think overall SMN is fine other then some tweaking of BP:Wards. The class is overall strong and will only get better with time. People just need to realize the potential of the class and when they do, realize we don't need buffs to be awesome because we already are.
