i want to make an interesting suggestion at least i think its an interesting one anyway.
well wee know from the movies and the books that gandalf the gray was very different
than gandalf the white gandalf the white is stronger than gandalf the gray
but in the game they are the same thing the difference between them is not that big
so i suggest to give him a new skill set when he is gray
1 the Wizard blast: should stay the same its like his basic spell and its very memorable.
2 Lightning sword: this spell should change it should be locational damage same animation but it should be a hit like in the movie the time he killed balrog,

3 Istari Light: this one should change only because i think its more of a gandalf the white signature spell

so i suggest it should be changed with this one a blast of light like in the movie Hobbit

the animation of the spell can be the one gandalf dose when he s won a battle the one he rising his staff.
4 Word of Power : now i know its its a very memorable spell of the bfme series but it looks to much powerful for gandalf the gray to have a spell like that so i suggest
it should be changed with a smaller word of power and it should look different not that big blue wave very smaller radius and maybe a fear effect for some seconds.
now when he becomes Gandalf the White wee all know he gets more powerful
so after he becomes white his spells changes they get stronger
1 Wizard blast: same effect more dmg.
2 Lightning sword: it becomes the one you originally had in the game so it is an upgrade from just a hit to this thunder he burns his enemies with.
3 Istari Light: the white blasst upgrades to the istari light.
4 Word of Power: the same old Word of Power
my suggestion is because i think gandalf the gray should be different than gandalf the white i think that makes him more unique and more interesting to play with.
