FFXIV Summons:
Ifrit, Garuda, Titan (Summoner)
2 Fairies and a Carbuncle (Scholar)

In FFXI Summoners, who had 17 different summons available, had a 2-Hour ability to unleash their particular summons most powerful AoE Attack, along with 8-10 different abilities per summon.

In FFXIV a Summoner (Anarchist and Scholar included) only have 3 summons apiece with only 5 abilities each.

Having the summoner class the "DoT" class feels like we're being really cheated out of what a summoner is actually supposed to be. Summons themselves need to be more of the focus on a "Summoner" class rather than the amount of damage the summoner themselves can dish out. I like the idea of having your character abilities tied to those of your summon.
