Now this is very interesting. I made a character like this back at the VERY VERY start of 1.10, when enigma was first introduced. An extremely high level bear + teleport to telefrag people (i got the name telefrag for it, too). I occasionally used chain-werebear-shockwave, but I found it was more effective to just teleport across people with high FCR.
However, I found that while the build was very competent, it was a one-trick pony, and had no versatility. I couldn't get close to wind druids, couldnt kill almost any ES sorcs, ect. Sure it was great for hunting bowazons, but I already had 10 chars that could do that. Heck I even had a polebarb with a full inventory of 5% FRW charms. So I started thinking. How could I modify this druid to make him more pvp applicable?
Then it hit me. The synergies for grizzly, and even HOW, are completely worthless in PvP. You don't need more AR, he already has enough. You don't need more HP, he already has enough. He's not going to hit people with ultra high defense unless they are walking, anyway, and his base HP is enough to get by with just recasting. So what did this mean?
It meant that the tele-summoner druid only requires 20 SKILL POINTS.
So what do we do with the other 80?
We already have a whompass 7k+ telestomp, so wind skills would be pointless. Shapeshifting wouldn't work out with the teleport theme. But oh, what about say, fissure/volcano/synergies?
Hence, I came up with the shaman after a while on the cutting block. I had that exact same kind of druid you have there, and the shaman was just a further evolution of the idea.'
I found that the hybrid fire skills made up for the weaknesses you have when you are fighting those hard-to-approach builds. You've doubtlessly noticed, if youve been using your druid that much, that you can't easily teleport to charging hammerdins or chargers, or pin down 200% FCR sorcs. Even with shockwave or garrows, as they do no damage on their own. However, when you can toss a fissure or volcano under them, it becomes something wholy different.
But don't get me wrong. The pure-summoner is fun to mess around with. Its just not nearly as efficient as it could be.
