1) Scorching Burst does not suck. It is an at-will attack that ignores cover and concealment. Point to an at-will any other PHB1 class has that does that. It can hit multiple targets. It is -very- useful.
2) Thunderwave does not suck. If you have a pit, differences in elevation, or simply terrain that is pleasing, it quickly outdamages -anything- that your party puts out. Oh look, there's a trap there. Thunderwave the monster onto it. Bam. Now you win.
3) Ray of Frost does not suck. Kite a guy in melee. If they get too close, refer to Thunderwave.
4) Magic Missle does not suck. With free basic attacks from a warlord, it's a decent damage attack that uses your primary attribute.
5) Cloud of Daggers does not suck. It, at worst, auto-kills a minion, and at best, does the most damage of all the at-wills.
6) Wizards require Int.... and.... um... maybe another attribute. Maybe Wisdom. Maybe Constitution. Maybe. But they don't NEED them to the level of any other class.
7) They can start with the equivalent armor of Plate Armor. 18 Int, +1 staff of defense, +1 Staff Fighting, +2 Leather Armor.
8) Did I mention Staff Of Defense?
You have awesome abilities. Spend less time complaining about their suck and more time not sucking at using them.
