Aura Tank?

[Althend]

If it is to provide an aura and increase the support aspect; make it being item then :o

For example:

Tank Linker: in aura of 1000 range, all nearby tank shares 20% damages
Active: the tank aimed by the item gets 30% slow during 5 sec

Magnetic field: In 1000 range, all allied and urself get +15% speed
Active: the allied tank aimed gets +50% speed for 5 sec

Dislocator: All enemies in 600 range get +15% damage
Active: the creep aimed by the item does +400% damage

Radiance: allied tank in 750 range gets mana and heal regen buff
Active: the aimed allied tank receive +20% of his max hp


And if u upgrad them, u get the active item effet!
