I, like everyone else who bought WLK, recently made a Death Knight (named Pareidolius, from the word "pareidolia"). And I, like everyone else, was dismayed to find that trade skills start at ZERO. So now, I've gotta run all across old-world Azeroth picking low-level flowers so I can make low-level crap that I'll vendor (fortunately, low-level Glyphs are desirable for everyone, so it's not a complete waste) so I can pick higher-level flowers so I can make higher-level crap...well, you know how it goes. The biggest mistake Blizzard made in this expansion (besides allowing gnomes to be DKs) was setting tradeskills at base level for new Death Knights. They're basically saying "here, go waste your time on something we could've easily fixed". How? Easy. Since Death Knights enter the "real world" at lvl. 58 (and immediately head to Outland), they should automatically start their new trade skills with 290 skill points. They should walk through the Dark Portal, get to a profession trainer, have Master-level crafting available to them to train, and be given 290 points right then and there.
Another way to fix this problem, and the skill point system in general (including weapons, defense, etc.) would be to give all players the option to go to a trainer and train up to the appropriate level, or pretty close to it. It's not fun to have to go and "grind" up your skill on something. Who wants to run around collecting materials, or even worse: buying them off the AH? Who wants to go stand in one place and get beat on to level their defense skill? On Baluki, I've been using nothing but daggers for a VERY long time. If I decided to respec to Enhancement (and I've been collecting gear for it, partly because I don't have a choice (WTF BLIZZARD? DID YOU FORGET THAT ELEMENTALS EXIST?!?) and partly to try it out) I would have to go wail on some low-level creatures to get my skill up so I can be effective in combat.
I'm sure Blizzard knew about this problem, but for some reason they chose not to address it. I hope they do some day, but it'll be too late for my Death Knight, because he's going to get his Herbalism and Inscription skills to 275 before he hits Outland. And he's going to hate every minute of it.
