| There's no reason for buying high level spells instead of several "cure light wounds".
Every lousy level 1 priest with 0 XP and 11 wis can cast "cure light wounds", but "heal" is a level 6 spell which requires a level 11 priest who had to survive many adventures to get that many XP and has to rest before he can cast this spell again. Healing is no factory product stored on the shelves, it takes effort.
In IWD2 there the prices depend on spell level, it's not calculated how much you actually benefit the spell in the current situation. Outside combat a few clw spells are as good as a heal spell, but when your tank is at 1 HP in combat you'd rather 1 heal scroll available instead of 1000 clw which heal slower than the tank takes damage.
I'm actually glad that the game has no time limit, nothing is as frustrating as getting stuck without knowing before it's too late.
I don't think you'll benefit from a time limit. If you play without healer you won't reach a decent total in game time anyway.
If "too easy" means you are missing lost battles and save and reload orgies: This is no arcade game which you have to practice in order to get far. This is an rpg, an adventure. See beautiful locations and dangerous monsters, meet good and evil people, explore the story with all its surprises, do big and small heroic deeds.
Fighting battles is only a side effect. Battles aren't supposed to be extremely difficult, winnable only with a lot of luck after several attempts and hours of thinking. You are supposed to use your skill in order to avoid that your party ever gets close to dying. The game is very long even without reloads, it doesn't need to cover its shortness by save and reload orgies like other older rpgs. |
