gugnir is a great weapon! maybe not for all you /mele users but its a great /mage sub weapon
Aye for soloing its amazing, shock spikes aftermath is cool, but for anything where you're in a party/alliance is terrible given the -10~15% defense down you'll lose when using this weapon
The shock spikes don't work for crap. Maybe if they increased their accuracy/duration/proc rate then it might be nice defensive bonus but they barely work on EP mobs. I was not impressed while helping my wife with her gungnir trials. Any mob that you'd actually need /mage to survive on would resist it in to the ground. So, I can't agree that it's a good solo weapon.
Also, after the August update, the best defensive weapon will also be the best offensive weapon because of the advantages item level gives you and particularly what main hand weapon's item level gives your wyvern.
And yeah, if they fix the def down overwriting angon thing it might be an okay weapon(when REM's are updated anyway). But they mentioned changing angon like a year and a half or more ago... Loosing hope that it'll ever happen.
