Summoner Spell selection
I play a variety of MOBAS including Lol, Smite, Heroes of the Storm, and Dota 2. In smite, instead of summoner spells you have these things callled relics, which you unlock the first one at level 1, and the next one at level 12. You choose your relic ( a.k.a summoner spell ) in the fountain, and can therefore pick your spells situationally, for example in lol if you are fighting pantheon or zed you can take exhaust, if you are against mundo you take ignite etc.
I think it would be cool if riot made choosing both your summoner spells when you spawn into the game a great idea. Tell me what you guys think
