A bladesinger is not usually going to deal a lot of damage in melee. Your best melee option is going to be green flame blade when there are multiple enemies. Your AC is high enough that you can also consider using booming blade and move away without disengaging and eat the OA. For high damage you are going to have to use real spells though. If you need a spell caster that does good damage in melee I would look at other options, including arcane trickster, eldritch knight or a multiclass with a dip in a different type of wizard (diviner or war magic).This is kind of my issue. I do want to be somewhat of a presence in combat; maybe not quite on par with a fighter, but a force to be feared.
I disagree that a bladesinger is not martial. It is martial but in melee it is purely defensive, not offensive, take a dodge action or at 3rd level pick up blur and you are a rocking a 24AC that the enemy needs to roll against with disadvantage. In pure melee combat, a bladesinger in bladesong will survive longer than any other character except a raging barbarian and even those two are close. While Fighters, Rangers and Palasins have more HP, the bladesinger will get hit far less and in melee this more than makes up for the hit point differential. The bladesinger will not do high damage though, her role when not casting spells is to tie up enemies on the front line and keep them busy while the rest of her party deals out the damage.
I think Diviner and war magic are better as a dip for a offense-focused melee build. Diviner gives you the portent which you can use in a strength build to make your GWM hit ... or make your enemy miss. War magic gives you an unlimited use +2 reaction to AC. This makes a 2-4 level dip in wizard pretty attractive for a melee fighter or rogue while getting all the damage and armor bonuses fighter/rogue offers with 5+ levels. In a strength build low level fighters should have a 21 AC with chainmail and the shield spell or 23 with chainmail, shield and the shield spell (compared to 24 for the bladesinger in bladesong or 21 for a bladesinger out of bladesong). The flip side is they will not have as many slots to spam shield and they don't get the constitution, acrobatics and movement bonuses from bladesong but they will do substantially more melee damage, especially the variant not using the shield.
