The new masteries are somewhat confusing, I can't decide which one is better.
The current season 4 masteries are clearly defined in one thing. The offense tree is made for offensive champions, the defensive tree is made for defensive champions, and the utility tree is made for utility (support) champions.
This may seem to be very obvious, but I am saying that because there is a problem with the new masteries. While the defensive tree is obviously tailored for defensive champions, the offensive and utility trees are rather confusing. As an assassin, mage, or ADC, I am obviously going to get the first four tiers of both offensive and utility tree (the defensive tree is now best exploited on bruisers and tanks, on hyper offensive champions you are better off going on the other two trees). The problem that is making me become confused, however, lies on the last two tiers of both offensive and utility trees.
As an assassin, which tree is better? Utility or offense? And as a mage? And an ADC?
I will explain. The utility tree has flat armor/magic penetration, as well as having two keystone masteries that seems appealing for burst champions (Thunderlord's Decree and Stormraider's Surge). However, the offensive tree has equally good masteries. Both Battering Blows and Piercing Thoughts seem better for late game for mages and assassins. Warlord's Bloodlust is a rather obvious choice if I am going for a crit build, while Deathfire Touch seems good for burst champions.
Those masteries are confusing because both trees have a mix of masteries that are useful for offensive champions, instead of one tree being focused on offense and the other on utility.
I can't decide which masteries are the better. I know that they are still on PBE, but it is important to make a decision now.
I generally like to play those champions as my offensive champions of choice:
