Beside the point. Ethan, these tables of conjugations and declensions that you brush off so quickly are essentially summaries of "real examples".
I'll get back to verbs. Let's look at their endings in other Indo-European languages.
Latin:
Present active: -ô/-m, -s, -t, -mus, -tis, -nt
Present passive: -or -r, -ris, -tur, -mur, -minî, -ntur
Perfect: -î, -îsti, -it, -imus, -istis, -êrunt -êre
Sanskrit:
Primary active: -mi, -si, -ti, -mas, -tha, -nti
Primary middle: -i, -se, -te, -mahe, -dhve, -ante
Secondary active: -m, -s, -t, -ma, -ta, -n
Secondary middle: -i, -athâs, -ta, -mahi, -dhvam, -nta
Perfect active: -a, -tha, -a, -ma, -a, -us

Greek-Sanskrit similarities: augment for imperfect (e-, a-), reduplication for perfect, some verbs' aorists having -s-, some verbs having vowel shifts. Some Latin verbs' perfects also have vowel shifts, -s-, and/or reduplication.
