Question to Cassiopeia mains
So, I used to main Cassiopeia back in season 3 and 4 when I considered myself a mid main.
Ever since then I became a jungle main, but recently I started to play her again, along with other midlaners, and I'm kinda rusty.
So to my question. I see that 55% of Diamond players use Deathfire Touch, 30% Thunderlord's and 15% Stormraider's.
Being the thunderlord percentage so high I assume there are match ups that Thunderlord's is favoured, though I reckon this could just be player preference, and I was wondering when should I go for Thunderlord's instead of Deathfire, if ever.
Thanks in advance.
