I just noticed (well, actually a while ago, but I just feel like making a thread about it now) That it is very hard to get to a high level without either grinding or becoming a jack of all trade. On my first character, once I got my main skill to 100 (2 handed) I leveled up excruciatingly slow, and by the time I got my other commonly used skills to 100, 1 handed, block, and heavy armour, I didn't level up at all. I stayed stuck at level 37. Later, when I tried to get the level 50 achievement (I'm kind of an achievement [censored]) I had to grind archery, smithing, and light armour until I hit the 50 mark. Basically I had to switch my playstyle from a barbarian to an archer. Does anyone else find this annoying? This pretty much limits my character to mid level content, (which isn't necessarily bad, imo, but still)
Leveling up is fun. When you level up after your build is finished, you get more health, more magicka and more perks. It generally makes your character stronger. It makes your character stronger faster than it makes your opponents tougher. The game generally gets easier as you level up more. You can splurge on the perks that you wanted to get but couldn't.
Yeah, you change your play style to level up, but you can always rely on your super strong core strength when things get hairy. Also, it's sometimes fun to try new things.
