Giving your Melee fighter some extra mobility with the Scoundrel/ Marchman's "teleport" spells is not a problem. Neither is giving your ranger one point in Int so that they can wear the +2 int lower body armor (Sangos or something?) and start casting buff spells like Oath of Destruction/Bless in additional to the resistance boost that these things offer (they can be enchanted with Rubies as well). Just don't expect them to throw Fireballs around at level 4.
