The Elemental Summons of the Sorcerer are VERY cool... However, they are also very limited in so many ways that you would think they should be available to sage/scholar classes before third class.
I have two suggestions:
My first being increasing the size of insignias. For sorcerers to have so many large AoE skills, its slightly disappointing for one of their most game changing skills to be limited to 3x3 areas. This is all the more disappointing considering that the elemental summons DOMINATE within the 3x3 area and become insane tanks due to level 2 insignia's ability to give elemental attributes to all attacks in the area (I.E. placing a fire Agni within a Fire Insignia = 1 damage to Agni even from biolabs monsters) Its a miracle in itself to get the elemental summons INSIDE of the insignia (considering that players cannot control the movement of elemental summons) but even if the summon stands in the insignia, most high level end monsters have enough attack range to stand outside the insignia and STILL hit the summon standing in the very center of the insignia.
It's quite sad that in larger parties (TI's in particular), insignias are pretty much useless because no one (and I mean no one for the most part) are trying to hear "Oh, I made a 3x3 area for you to drop the 20 of the monsters you are tanking."
Please, make the insignia's:
lv 1: 7x7
lv 2: 9x9
lv 3: 11x11
If you do this, many things may happen:
1: More people may want to become SUPPORT sorcerers
2: More parties would WANT sorcerers other than being SP slaves
3: Sorcerers would actually USE their summons to assist in battle and not simply be used for active/passive effects (I.E: "I only have my Ventus out because it gives me 1 second fixed cast reduction... Other than that it's useless..."
4: The elemental system MIGHT actually begin to come alive (So you don't have people years after Elemental Summons have been implemented saying "OERRR-MAH-GOD! What is that thing? Does it fight?" They'll just know...)
5: More interaction and coordination with warlocks and sorcerers (I'm sure the intention was for wizards and sages was suppose to be much better considering that sages can actually BOOST the affects of a wizards' spell, yet how often did you really SEE a sage casting Deluge under a wizard?)
6: There would be a lot of people buying skill resets trying to make use of the summon system (I mean... come on... this is a win-win for both sides...)
If this cannot be done, at least acknowledge that summons are obtained when becoming 99+, however they FAIL at killing most monsters that are 99+. If they are not meant to fight high level monsters (which they actually CAN do currently given the right yet rare positioning of insignias), then please do not let make them targetable by monsters.
