Guild Wars 2

I noticed that some professions / playstyles have a really hard time to tag enemies, even though they do contribute in a meaningful manner. It seems that, while doing a bit of damage, people who specialize at conditions (Staff-Mesmer for example) or support tag much less mobs than those who go for pure power/prec/crit.

I can imagine that it’s quite difficult to find out which action should count as meaningful contribution, so I tried to find a simple approach:

analyse how much actions a player does during a battle (action in the sense of interaction with friends and foes). These would count as 1 Interaction.

Debuff = 1 Interaction
Buff = 1 Interaction
Damage = 1 Interaction
Heal = 1 Interaction
Ressurect = 1 Interaction / sec

who gets loot:
—> Do 8 interaction with an enemy to get loot
—> Do 8 interaction with an ally to get loot if he kills someone

yes, this would also reward players who do bad interaction (like protection-buff to people who don’t need one in the backline – bad example) but that would be better than not rewarding people who support or go for damage over time effects imho.

What do you think?
1.) Do you feel the same way I do about contribution and the resulting loot?
2.) Can you think of a simple way to count contribution for all professions/playstyles?
