How does any of these changes in any way, shape or form equate to this absurd example you're offering? .
In more than one. Thanks for asking and goddbye.
I take it you aren't going to elaborate on that, or rather, can't. You clearly aren't here to offer constructive criticism or get a real debate going, you're just throwing a tantrum because Larian is taking some freedom in their approach to certain systems that wether we like it or not, will be most welcome by many players. You're also quick to dismiss others' points when they disagree or yours are challenged, your opinion is not more valuable than the others'.
Realistically, the only of these changes that will affect those of us who wouldn't normally want to benefit from these tweaks, is the one that touches spell slots when multiclassing, we don't know the severity of the changes yet, but worst case scenario, multiclassing will be slightly stronger than it should be for the price you're paying, hardly the end of the world.
Also @Darth_Trethon, multiclassing was one of the most requested features for this game, having it be stronger than it would normally be is clearly preferable over having it completely removed, suggesting otherwise is kinda ridiculous.
Just be reasonable guys, I don't personally like these changes myself, but they make sense and I doubt Larian will take them so far as to be game breaking.
