Summoning Magic concept (video!)

[VeranRamaden]

I think that if someone was within the area, you could not summon the same primal would work instead of instanced area. Also only one summonable at a time in a given area. That way keeps with the lore(ish) and wont spam kill peoples computers.

Example:

p = party
| = maximum distance
<--> = okay area
xx = not okay area

|<---------p--------->|xxxxxx|<---------p--------->|

If you were ok on distance, you'd get the whole shebang.
But if you were to close, the possibly the attack doesn't have a source.
Just a random fireball in this case. But that's lame.

OOOOO Idea!
Instanced area -> the choice to summon ala old school (like the OP) or pet style
Open World -> only pet style.

It'd be a win win imo.
old school would take longer but receive the buffs, just the summon would be stationary.
Could have a battle regime were you choose X amount of spells to cast.
And pet obviously like XI. Essentially you get the exact same things except can do physical dmg too.
