Im gonna say havent read much of other peoples responses yet but I have to say I absolutely LOVE the puri.....EQ2 shaman was mentioned as a reference and I was an even bigger fan of the EQ2 shaman.
Puri is fun to me juggling the symbols with the wards. If the symbol is used properly you can pretty much keep everybody alive easily but its challenging especially with the burnout 8 secs with it being reduced. I personally didnt put any points into have a % towards burnout being removed early cause it seemed unreliable to me while others might find it worth while.
The only things I would change is the 1st AE used the current burnout and causes it and I think it shouldnt be affect by or cause burn out due to how weak it is....it should be spamable. The second AE Symbol of the hearth i think its called.......well im not sure what to do about it at all but it is also affect by burnout so becomes very ineffective during my gameplay even though I have it on my hot bar ready to use.
Maybe to make puri more enjoyable they can change the burnout effects slightly to instead of blocking the symbol it can deminish the symbol strength when recasted too soon. Not entirely sure HOW to make that work properly but it sounds like it could be interesting.
