Teleportation Spells from a Drunken Madman

(the following is a drunken rant from a university professor on conjuration. All of the following is true though highly opinionated)
You know what's fucking bullshit? Conjuration runes, like why the hell are the most fun spells locked behind twenty bloody layers of bullshit?! For one, if you put even the tiniest dent or writing in the rune it all falls apart. Every other rune works just fine with a bit of writing, but one extra line in conjuration and it's all torn apart. What the fuck? I tried to prank my bud by writing a different rune over the conjuration rune, and it didn't work because of that stupid ass rule. What the hell? Though I gotta admit, the fact that failed conjuration runes just fizzle is nice, be a shame if a haywire teleportation spell sent you to somewhere very far away from the initial destination...Hey? Where are you going? I haven't even mentioned the summoning rune crap!
