I can see where you're coming from but your point only really applies to anyone who play the exact same kind of playstyle and took Oddity XP every time. For those who wants to play radically different kind of playstyle, either system works based on what kind of playstyle they want to play. For example, in my first 2 runs I use Oddity because they were subterfuge-oriented, with the only difference is that one is a jack-of-all-trades who tried to do a little bit of everything, while the other is mostly focused on PSI. On those 2 runs, I didn't experienced any of your described problems, since I'm perfectly okay with slower leveling and I'm not at all sad about low drops (except perhaps for my first run, since I haven't done some of the side-quests I was forced to grind for oddities in DC, and even then I don't have any problems with that).There are two distinct points here:
1.) Oddity is tuned to be harder (slower leveling) than classic
2.) Oddity is something novel and adds to the exploration/gameplay experience
How does oddity add something substantial, beyond being a cool gimmick for the first run?
If I was gonna explore everything, going oddity doesn't change how I'll play in any way, except maybe making pickpocket more valuable (and being sad about the aforementioned drops, like pig snouts) .
Now, after doing subterfuge runs twice in a row, I'd like to play a zero stealth, *maybe* zero lockpicking/hacking, assault rifle-toting juggernaut in heavy armor. Obviously, the Oddity system wouldn't work as good as for characters more suited for exploration like stealthy-ones, so the classic system is the way to go, especially since an assault rifle-toting juggernaut will be facing combat head-on instead of avoiding them like a plague. Will the problem of getting to the max level earlier bothers me? Maybe. But I haven't yet experience such type of playstyle while using classic XP to the very end (only an aborted run after my laptop died for the nth time), so we'll see.
My point is that Oddity isn't just a cool gimmick for the first run. If your first run is on Oddity and it wasn't a rogue/thief kind of playstyle, then if you ever decided to try and play a thief who breaks into everyone's private room and rummage through their purse, you wouldn't be doing yourself justice by playing on classic XP. And not just thief playstyle, really, I think Oddity works perfectly for characters who specialized less in combat, like talky characters. Because, like I said, Oddity isn't just tuned to be harder like you said, it's also fine-tuned and much more supremely paced so that players can experience certain content *exactly* at the levels where they can find them still challenging, but not outright impossible either. And when I say content, I didn't mean it in just terms of combat. For example, since my first run hasn't done some of the side-quests, I was severely under-leveled by the time I get to the Institute and I was completely unable to face the Lunatics at the mall in combat. And thus, my only option here is to stealth through the crazies and try stealing the figurine without being detected. Along the way, I was able to get my hands on some of the oddities and leveled up once. Since it was a jack-of-all-trade character, it would be pointless trying to invest in any of the combat skills, but since I was decently invested in Stealth, I just put most of the points there and hope I can sneak easier now after leveling-up. Lo and behold, I WAS able to steal the figurine without being detected. I will not forget how my heart beating so fast as I put my character in a blind spot near the statue, click as fast as I can to the statue and then back to the blind spot, all before those Lunatics near it get their detection to orange, in real time.
Now, if this is classic XP, my only option would be to try and grind for a level or two *before* attempting to steal the figurine. Had I not leveled up that one time thanks to Oddity, the Lunatics would surely gets to orange detection and bumped into me.
