As a summoner, you may be required to do several different things during dynamis.
Some of these roles including:
- Nuking (With magical BP's)
- Meele (Avatar meele BP's)
- Healing (With spells + BP's)
- Support (With spells + BP's)
Nuking
Generally, the only time you'll need to nuke, is if something happens to the BLM's, or if its required on some NM's (Were theres nothing for you to do but nuke.
If the BLM's are doing timed nukes, since the casting time on Avatar BP's is awkward/different, it is NOT advisable to join in on nuking these.
Nuking is with avatars is what you'll do on mobs such as THF, PLD and possibly MNK (When they are being kited)
Meele
You'll find yourself using meele BP's on most of the normal monsters because they tend to do the best meele damage. Without merits your best bet is to use Leviathan as it is a single hit, high damage BP.
On statues, DO NOT meele these, they have very high pysical defence, and have really annoying TP attacks.
It's genrally advised to release to release your avatar if its not doing anything, this prevents it from attacking anything you have hate from (You'll rarely ever get hate, but just incase)
Healing
You'll probably find yourself inplace of a healer alot of times, depending on how many WHM's show up. Fortunatly, healing in dynamis isnt that bad, unless your a tank party. Curaga II should suffice once 3 or more members require a Cure 3. Beware of pulling hate on monks (Ushually during 100 fists, you'll drop almost instantly).
Protectra II and Shellra I or II (depening on your level) should be used, and make sure your ready with those status -na
Light Spirit
If you have reasonably good (preferably capped) summoning magic, Light spirit can become an invaluable tool in Dynamis. Once you have several members starting to dip below 50% HP for some reason, pull out your light spirit and make sure it is facing towards the mob everyone is fighting, the light spirit will most likely use Cure V or Curaga IV on your party/alliance members.
The higher your summoning skill, the shorter the delay for the spirit to heal. If you have a White Mage in your party, you probably won't need to use Light Spirit because the White Mage will be able to bring them out of the orange/red faster than the spirit can.
Support
Before level 70 Summoner, you will be stuck in this role, as well as healing (unless you have diabolos, then Nether Blast would be nice every now and then). Post 70 depending on the situation you may be required to use Earthen Ward/Areial Armour and several other AoE buffs.

Quick Note
------------------------------------------------
Raising
During dynamis (Mainly in Cities) people dont like eating R1's, BUT if it is a critical situation (e.g. Trying to get people up as fast as possable to do the final boss of the zone before time runs out), all types of raises will be used. During Dynamis - Xarcabard, give out as many R1's as possable, as we need to get people up as fast as possable. (It also acts as an incentive for people to get, and use Reraise II equipment, increasing the speed of the run)
I know this isnt a complete guide to dynamis as SMN, but it should give you a little headstart if you have no idea what to do in Dynamis as SMN.
Any additions/critisism to this is welcome ^^
