Spirit changes?
That’s nice! But sorry, these kind of dreams (player suggestions) can’t come true!
Additionally, the tooth fairy does not exist.
I like the idea you are moving towards, but your suggestion doesn’t really fit into Anet’s model. Anet doesn’t want players to specifically target an ally and then hit skill A to heal them or skill B to apply boons. Any skills that do such will be done indirectly, like a ground targeted AoE. Other than that spirits are the same as what you suggest in their current state. What they really need is more survivability/better boons to compensate for them dying so fast, or to operate like warrior banners to make them viable.
White Devil: I’d rather put forth an idea that has a minimal possibility to inspire developer thought than to not take a chance at all, especially if I’m unhappy with the current system.
Additionally, I’d argue the Tooth Fairy does exist, in spirit at least.
Artemos: I realize that it’s a little out of the box but that doesn’t mean we can’t reconstruct the mold. It would allow for a layer of micromanagement unique to the Ranger. That said, it would still allow for the current system to remain for those who don’t want to mess with the micro.
Hitting your next point, I forgot to mention in the main post that they are untargetable (except for retaliation). What I did not forget to mention was that the effects/boons would be scaled appropriately to the new system.
I fully agree that survivability is a real issue with spirits, but I believe ANet made the adjustment because with the current system that was really the only appropriate way to balance out the potential power of the skills (especially since their effects stack for each ranger); if they were to nerf the boons instead of survivability you would still be receiving the same amount of effect as now just within a longer span of time, you can see the problems with that. So, the only way to get away from certain limitations would be to move to a different system.
I can see how operating like a banner could work, I’m curious to hear more about what you think on that topic. Also, if you disagree with any of the above let me know why, I’m fairly new to Guild Wars so I’ll take any edification I can get.
