MonsterSpawn Group - Improvement

Hello Dears,

How are you ?

Here I will make a new suggestion for the system ( MonsterSpawn_group ), The suggestion is :

Make the possible random map spawn:

Example:

		<!-- Group: Invasion : 2.5 Invasion {Aida,Tarkan and Icarus} -->
		<Group

			Index="33"
			Duration="30"
			MapNumber="33;10;8"
			BossMonsterIndex="309;63;77"
			BossMonsterName="**** Maine"
			AllowMove="1"
			SpawnNotice="The 2.5 Crafting invasion started now !"
			DespawnNotice="The 2.5 Crafting invasion has ended now !"
			PreNotice="The 2.5 Crafting invasion will begin in %d minutes..."

		/>
		<!--  -->
		<Group Index="33" EnableRandomMap="1"  MapNumber="33;10;8">
			<Area StartX="50"   StartY="103"  EndX="57"   EndY="114" />
		</Group>

This is better settings for invasion management ?

Thanks in Advanced !
