Wrong. If you want to give up the most useful power from your primary class then by all means, do so. It seems pretty obvious that this is in an attempt to stultify the discussion with low-brow, superficial quips. You're completely ignoring the inherent design of emergent complexity within the class features and powers. When coupled with Action Points as a standard feature for Player Characters it allows for power combinations of the likes that characters have never possessed before.
Multiclassing provides characters with access to powers from other sources. Since power sources and character roles are well defined (unlike previous editions where copy n paste was all the rage), a multiclassing character can viably function in multiple roles. Access to alternate power sources and role features is most useful when it fits a character's intended design. This coupled with emergent complexity allows the character to function outside of their original role but not to outperform/outshine a purist (something that 3e couldn't claim).
Let's put it this way. A 4th-level character with a multiclass training feat has one 1st-level encounter power of his primary class and one 3rd-level encounter power of his primary class. If he selects the Novice Power feat, he can either:
1. Replace his 3rd-level encounter power of his primary class with a 3rd-level encounter power of his secondary class; or
2. Replace his 1st-level encounter power of his primary class with a 1st-level encounter power of his secondary class; or
3. Replace his 3rd-level encounter power of his primary class with a 1st-level encounter power of his secondary class.
Given that he has already chosen the 3rd-level and 1st-level encounter powers from his primary class, they can't be too shabby. In fact, they would probably be the powers that the player feels are either most useful or most appropriate to the character. Hence, it is not correct to say that the best power from the seconday class replaces the
worst power from the primary class. It is in fact replacing one of the better (if not the best) powers from the primary class.
Now, I do recognize that there is an advantage in gaining a power from another class. What is not clear to me is whether the relative gain in utility is worth a feat (remember, we're replacing the best with the best here). As previously mentioned, I think that one feat for three swaps (replacing the best encounter, utility, and daily powers of the primary class with the best encounter, utility and daily powers of the secondary class) is about right. Alternatively, a single feat could give the player the option to use either of the best powers from his primary or secondary class (i.e. the player selects an encounter power from the seconday class. Once per encounter, he may use that power by spending an encounter power from his primary class of that power's level or lower. So, if he selected a 3rd-level encounter power from his secondary class, he could use it once per encounter by spending his 3rd-level encounter power from his primary class. If he selected a 1st-level encounter power from his secondary class, he can use it once per encounter by spending his 3rd- or 1st-level encounter power from his primary class).
Of course, this assessment is based on what I know of the powers that have been released so far. I'll make a final decision after the rules have been released and I've managed to play around with the system for a while.
