None of my character are over level 40 ): but that's because I hate doing everything on one character. Each of my characters have strict rules, where my Ranger character doesn't use swords (or daggers, ect.) at all. just bows, and eventually, crossbows!
Ever since I started being more stricter and limiting my characters to one combat skill in Oblivion, I've kept the tradition.
I only have 2 saves for my Main Characters. The rest I can cope with accidentally deleting or something. although, I do play on ALL the accounts I've made, and not just that I've made them for the fun of making them. Each of my characters have done something another hasn't, if that makes sense?
A bit OT, but it makes little sense to me that your ranger would jump to cross bows.
Weren't crossbows basically regarded as ranged weapons for dummies?
Skilled bowmen had better accuracy, precision and range with a good bow than crossbow bolts. The great advantage that crossbows provided were impact power and a massive improvement in accessibility.
I'm the same way about characters. Very few have repeated the quests of another. There is some minor overlap but I have:
(1) Nord - MQ and Civil war(Stormcloak), might bring him around to the companions
(2) Orc - Companions, Civil war(empire)
(3) Dunmer - college of winterhold, MQ*
(4) Khajiit - dark brotherhood, thieves guild just to radiant quests
(5) Bosmer - thieves guild
(6) Argonian - daedric quests, began MQ
(7) Breton - no faction quests, eventually will do CoW and DB
Eventually I will make an omnipotent character but it took me a LONG time to get around to it with OB and I expect it will be just as long with Skyrim (if ever). My ill-fated destruction archmage is stuck at level 10 and doesn't get much playtime anymore, but otherwise I've played each toon quite a bit and revisit each periodically.
