Roleplay-wise features of specialist mages

Hello! What distincts Your gameplay for Necromancer from general Mage gameplay (or Conjurer, etc)? There are no difference, we still use same spells for 90% of time. Additional spell-slot\level for specialist is only a number, but quantity is not a quality. You will remember the gameplay for Thief or Bard cause it's can't be reproduced by Fighter or Monk and vice versa. Sad, but all specialist mages gives same experience, like kits of any other class. As D&D tales Illusionists is really stick to illusions, not Fireballs. Choosing specialist gives something to roleplay only if You force yourself to constant use of specific school, but You can do it even with Sorcerer. There is a good way to bring true specialist experience! They should use spell of choosed school as it was one tier lower than before. So, level 7 Necromancer should get Animate dead (originally on 5th tier) as 4th tier spell instead of wait to level 9 as general Mage. Most spells aren't used often due to strong concurency on every tier, but against spells of lower tier they shine as brilliants. Do You feel attracted by Your school now? I am! >:) No more "same spells\tactic every walkthrough". Technically, it's better to do in IWD2 way (D&D3), where engine allows You to learn and use the same spell at different tiers based on character class. If You like the concept, then comment and involve devs to conversation. ;) If impossible, then thanks for reading to that point! p.s same topic already was removed without notice so this is a clone. If it's content violetes any forum rule, it's not intentional.
