Wizard question

[ReticentTarsier]

So this is my first character on here. I played back on live up until PoP. Had a 54 bard as my main.

Decided to try a wizard on here, mainly because it's different than a bard, I wanted to be able to port, and dont care to play a healer.

I just hit level 30, and am very underwhelmed by the wizard. The mobility of ports is nice, but soloing entails a ton of downtime. Grouping is better, but it feels like every other DPS class does the job better than I can. I am nuking once or twice per mob for 240ish (assuming no resist, which I seem to get a ton of) while melee characters are pumping out far more damage (especially if they're twinked) with no mana concerns.

So does anything change at higher levels, or is this just what being a wizard is? If it gets better, I dont mind sticking it out, but if this is just how it is, I will likely reroll something else. I'm just not particularly enjoying the class.
