5 thunderlords on my team

They just need to rework all the pure damage masteries. They're not really creative at all and thunderlords is easily the most reliable with a few exceptions like Deathfire Touch on Brand.

Really I feel some of the masteries are really good on certain based champions like:

Stormraider's Surge, Windspeaker, Grasp of the Undying, Bond of Stone.

While other ones like:

Warlord's Blood lust, Fervor of Battle, Deathfire Touch, Strength of Ages.

normally get trumped out by Thunderlords

If you didn't have thunderlords then it would be 4 thunderlords on your team.
