Yeah, nah, no fucking way did you need to change gear every second level or anything like that; gear in D:OS1 was OK for a long time, and even if there were uniques that were trashy, it was nothing like in D:OS2 - not anywhere close. It's entirely possible to argue that there was a degree of bloat, and it definitely used the same (bullshitty) standard of leveling encounters even when it makes little sense (i.e. a human guard doesn't just stay as a human guard, they all somehow increase in power as the game progresses; the orcs are a perfect example of this, since you meet some already at level 1-2, and then meet the same associated force of orcs later and they're suddenly much higher level).Bull. Shit. D:OS1 didn't have anywhere near this much bloat in terms of numbers. There's even mods specifically for tuning it down to D:OS1-like numbers. I can't vouch for D:OS:EE, because I never finished it, but D:OS1 didn't have anything nearly as bad as this.
Both were bloated and items had to be swapped every lvl. Im not sure how to compare bloats to say that one was worse than other.
Maybe you didnt swap armor every few lvls in dos1 but physical dmg reduction was huge.
But while I think that's a shit way to level encounters and I prefer a much flatter curve that is modified primarily by means of attributes and statistics (i.e. you should get extremely little health unless you actually increase your health-giving characteristics, etc.), I don't think it's necessarily bloat, especially not when this strategy is endemic, and it is certainly not on a level even vaguely comparable to D:OS2, especially by the late game.
