In most fights it is not that important. Beam and flight abilities often have more of an impact. And as a party consists of 4, and some other not uncommon classes can have the spell too, I would not decide the choice of the class because of Longstrider.
Initiative and movement are king in a tactical game. It doesn't matter as long as you have someone who can provide it who isn't a warlock, since Warlocks not only do mid damage but don't provide buffs to the group anyway and because of that I would never choose a Lock over a Wizard. Again, it's a great class for amateur and new players since it requires nothing from them in terms of knowledge or skill to play.
We just recently finished a multiplayer honor origins run where one person selected Wyll, who went through multiple re-specs through different players (the rule is you have to retain at least your origin class as base class but you can multi class) - Wyll in all permutations did the least damage, had the least affect on combat, and spent the most time dead. Astarion ended up multi classing into Ranger and provided Longstrider and did a ton more damage overall, at range, while also providing a lot more tactical usability and being a solid rogue.
The other two classes were La'zel who went straight fighter and proceeded to murder everything in melee, and Shadowheart as a Tempest Cleric who also murdered everything.
In every sense the week spot was always Wyll who was just not able to provide any solid AOE or group buffs until one of us just multi classed him into a Sorlock (2 Lock/10 Sorcerer) and then he was at least decent.
Granted, everyone in the run (except the person who selected Wyll) was at 2k+ hours in game so it was an experienced group.
I don't exactly know what you do mean with "What?",
What does this sentence mean - "In adidition, no class in this game needs genies to get along." genies?
