Forge system sounds very exciting because I do enjoy RPG elements. Just keep in mind that people who don't like dealing with cards and builds and stuff like that are still effective, most cards are just side-grades and alternate boosts to play. I still use Hans' original card that speeds up his recharge, Kon's first card is still deadly as it gives him an 8 second recharge with an aleph boost, I still use all the basic Wardog cards that give them a flat healing boost, I still like Lycus shield recharge (but I have a rare one), etc... The characters are still plenty effective with their base cards, but some people may want to mix things up to make their personal play style more effective. But Lv0's can still be effective with what they start with.
