Defense Tree for AP Champions

[quote=tek9420]I don't know about any of you, but I just had an epiphany about AP Champs and Mastery tree. We all know the basic 9 for offense, but what if, and stay with me on this, we take the 21 and put it in the defense tree? this idea first assumes your one of those people who always takes an Archangels staff, no matter what the champion. If you put 21 in the defense tree, you can use cleanse (for all the advocates), you get the extra 2-4% ability power with ardor and not to mention all the defensive buff (because you know you're fluffy) (for Vlad, extra AP and health buff from both ardor and Vet Scars). What made me realize this is the simple mastery, Strength of Spirit. With you as an AP champion I guarantee you if you you will have upwards of 4k Mana with Archangel's Staff and Rod of Ages, and I had upwards of 75 Health Regen. I then started thinking about the other benefits. Why you can go without utility tree: Perseverance - Mana regen and Health regen you get from Arch Staff and Str of Spirit are better Expanded Mind - Nice boost for mana, maybe instead of offense tree Greed - meh, its just to fill an extra for me Meditation - do you need more mana regen? Utility Mastery - dunno if you use it, but your not jungling, are you? Quickness - meh, space filler Blink - sure, nice for flash but rare use Intelligence - great early game, but I use cooldown reducers (no use for it late game) seems a waste of a whole tree for so little Presence of master - Nice, dunno if it outweighs the benefits I realize some of you like the cleanse, ghost combo, so I suggest maybe takin the 9 and putting it into utility with ghost, perseverance, expanded mind, and whatever you want for the last (I'd do greed... space filler) Any Thoughts?[/quote]

[quote=Visfarix]Yes I use the Defense Tree on my Anivia build always. I made a thread about this comparing the Defense Tree vs the Utility Tree earlier. Dunno where it is now... Anyway Defense Tree goes great on a lot of AP champs that specialize in burst/nuke damage imo, and those that stack MP with archangels, etc make great use of the Strength of Spirit mastery. IMO usually the Utility tree is used simply because it's such a great crutch for weaker players.[/quote]

[quote=Trojan995]Kennen is an AP (or at least AP the way most people play [not me]) carry that uses the defense tree. The utility tree is close to useless for all the mana it provides. However, kennen should never grab Strength of Spirit because he doesn't have mana. Instead, I usually go for the dodge chance and then the move speed on dodge masteries, though the names currently escape me.[/quote]

[quote=Freki]well you could have realized it before ;) and also you could realize that doing a 9 & 21 repartition is not mandatory[/quote]
