L'Associate Game Designer Ryan "Realz" Masterson è intervenuto in una delle tante discussioni in merito su reddit per raccontare come il team sia arrivato a questa decisione durante lo sviluppo.
L'idea che ha generato il Cavaliere della Morte è la stessa di Kazakus, creare la Zombestia da una una scelta ristretta di opzioni, ma in seguito fu ritenuto molto più divertente usare le Bestie già esistenti in gioco.
Subito però si è presentato un problema: era fin troppo facile che su una singola carta si accumulassero tante linee di testo che ne rendevano la lettura difficoltosa, specialmente su cellulare, e quindi hanno dovuto revisionare tutte le possibili combinazioni in tutte le lingue disponibili. Se avessero dovuto ripetere questo procedimento anche per i set futuri la mole di lavoro sarebbe diventata insostenibile, e ciò li avrebbe anche incentivati a non creare Bestie dai poteri complessi.
Secondo Masterson la scelta di tenere questa versione di Rexxar ne è valsa la pena per poterlo portare nel gioco.

I don't post very often, but this is a topic near and dear to my heart, as DK Rexxar is one of my favorite cards, and one that I personally spent time working on.
We deserve an explanation.
It's a bit of a long response (story time!) so for those who are interested, try to bear with me.
During KFT development, some designers thought it would be cool if DK Rexxar did something similar to Kazakus (create a custom spell) and could stitch together two beasts to make a custom one. We talked about how that could work, including considering making custom minions exclusive to DK Rexxar with simple abilities that could be interesting when combined (like Kazakus). As you know, we ultimately settled on the existing set of beasts to represent the tools DK Rexxar has at his disposal.
One major concern was the text. If you imagine combining any two cards with longer text, 4 lines from each becomes 7-8 lines of tiny text, and needing a magnifying glass to read a Hearthstone card (including and especially on mobile) would be a bit silly. With this in mind, every combination needed attention, and since every localized language is different, different languages had to settle concerns with different combinations. Moving forward, the number of new combinations introduced would grow (and grow and grow) with each expansion. We also would either have to restrict ourselves and never make a complex Beast with a long text box, or exclude cards on an case-by-case basis.
Given the above, we knew we couldn't make a version of DK Rexxar with future updating. We gave DK Rexxar a set pool of options like Kazakus, but this time the pieces would start off as existing recognizable cards before they're combined.
So we had to decide: Should we still make this card? We thought (and still think) the answer is absolutely - Yes! We wouldn't have as many cool cards in the game if new ideas were tossed aside at the first sniff of imperfection. DK Rexxar is really fun, and we hope players agree that the version we have now is definitely worth having in the game.
