If there were a symbol next to the spell then this problem wouldn't even exist. Symbols are learned very fast because they aren't affected by a language barrier.
No one is saying that there shouldn't be icons. Icons would make it easier to recognize the spells
even for native speakers, just because an icon is a compact, colorful,
semantically meaningful image instead of a long plain-text string. It's just better in every way. But we aren't Nintendo and brainstorming solutions here in this thread or our community won't do anything.
The real question for us is not "should there be symbols or not," but "what do we do if they never introduce any symbols," and I strongly believe that "ban Hero because it's not fair to players to have to figure out the menu" is a silly, groundless solution.
As someone who speaks 4 languages (what kind of an argument is that even?)
It's context. It isn't anything special to speak multiple languages and certainly doesn't take a "genius"--it's just a matter of practice and exposure. I know these languages just because I happened to spend the time learning them, and being exposed to people speaking them. I don't have any (much?) natural affinity for language; it's all time investment, and people who are dedicated to playing the game internationally can make that investment.
Note also that we aren't talking about learning a different language, we're talking about learning
a handful of static words, with players frequently knowing
months in advance that they're going to be traveling. Unlike something like top-player physical reflexes, which are hard-limited by your genetics, the ability to associate words and symbols with animations is common to nearly everyone.
It's really no different at all to picking up on subtle animation startup cues, which is something that fighting game players do all the time.
There is also a difference between speaking in a causal conversation and having a moment to translate
If you honestly think that the fraction of a second that Hero players bring up their menu is enough time for a non-native speaker to instantly recognize 4 gibberish terms and their meanings
Casual conversation is even harder because you also have to manage context and words that you definitely don't know.
Half of the spells aren't even words
in English. They may as well be symbols.
Like, for the longest time before I got to play Hero, I believed that Thwack actually matched with the Hatchet Man animation. There is no semantic relationship between word and meaning here. Why is Thwack the name of a fast floating black orb that can insta-death me? No idea.
