That's a pretty nice breakdown, but the importance of Lone Wolf + Glass Cannon also functions on a different level:
Pro - Increased AP for a single character gives you much better maneuverability. You can move into position and still have enough AP to attack (instead of moving and ending your turn, eating several attacks). You can also use that maneuverability to escape from dangerous situations, flank, and kite much more easily than a standard character.
Con - Not as many cooldowns refreshing. This is a pretty huge penalty, since each additional character is another set of cooldowns that can be refreshing, allowing you to activate far more special abilities within an equal amount of time. Also fewer summons.
In summary, I think Larian did an excellent job making Lone Wolf + Glass Cannon a completely different playstyle that adds new dimensions to your tactics.
