I was curious about everyone's favourite sphere in the game…You can say what's your second favourite as well if you want…just give a few reasons for your vote (characters you like are in that sphere, cards you like, combos you like playing are in that sphere, a specific aspect of the sphere itself, anything)
My vote goes to Tactics : I love the fighting mechanic of this game, it's simple, fast and very enjoyable. Moreover most of my favourite characters are in the Tactics sphere (Legolas, Hama, Landroval, Bard, Boromir, Beregond, Elladan), I like eagles a lot and I love to put one (or two) blade of gondolin on Leoglas to progress more by killing than by questing, I also enjoy Hama+blade of gondolin+foe hammer.
My second favourite sphere would be Leadership : I just love to have resources to play everything just when I need it. Sneak attack and Steward of Gondor are two of the strongest cards in the game (I love them). There are a few characters I like (Aragorn, Boromir, Imrahil, Elrohir, Theodred, Faramir). One of the features I love is boosting WP with faramir (sometimes twice with ever vigilant).
