Syllabaries are pretty useful.
en.wikipedia.org
Japanese Hiragana uses 46 symbols for example and Linear B uses 187 or 87 depending on your count.
One would need separate symbols for "bag", "beg", "big", "bog", "bug", "bad", "bed", "bid", "bod", "bud", "bead", "bide", "bode" ... etc for English. There are over 10,000 syllables in English ignoring some syllables that don't appear in actual words but come from Latin renditions of proper names from other languages.
But pretty sure English wouldn't develop if Latin developed differently (which means no Norman French as we know it) instead we'd have languages that don't have 10,000 syllables. And even if languages did develop with over 1,000 syllables, a syllabary would be infinitely better than a cumbersome system where each word needs a new symbol.
