1. Warlock's fight abilities. Don't believe scrolls of misinformation! They are telling lot of nonsense, especialy the W&W ones.
Warlocks are excellent fighters but they need the Heroic Might (Spirit Magic, level 4) boost. You can train their fighting skills and the skills will improve. Right, a warlock is a worse fighter than, for example, an assassin at given skill and ability levels but the Heroic Might spell will compensate it.
You can even give a warlock the 2nd Weapon skill (the warlock must be a member of the Fighter's Guild) because there exist a left hand weapon available to warlocks in the game: Main Gauche. Your warlock will have 2 attacks per round.
Train your warlocks in the Dagger skill. The best weapon in the game at all is a dagger (Wizard Blade). Moreover, Main Gauche is a dagger, too. Main Gauche +2 belongs to the best 2nd weapons in the game. Better is Wakizashi +2 (sword), the best is the Assassin Dagger (dagger, but available only to thief classes, not ot warlocks or warriors).

2. The phased combat. It's an attempt to allow the player to use brains instead of quick fingers on his mouse. The base idea is to allow all monsters only one attack. Then the monsters must wait until you decide for some action. Then each monster gets one attack again. And so on.
That means that you have plenty time for decision what to do. Once the monsters have attacked, they have to wait until you decide for the right spell, target the right monster and cast. Only then they can continue attacking.
In practice, the system makes the monsters lame. Only the very fast monsters are dangerous sometimes. The rest of monsters will wait until it gets killed.
