I don't know what u want to show there but his grammar is good , no errors
Oh, don't get me started. ^^
1. "on the new map"
2. comma before "which" (non-restrictive relative clause)
3. "the time limit"
4. no comma before "there"
5. no comma before "but"
6. "had been destroyed" (more of a stylistic error)
7. "to make the fight also focus on pacing" (word order)
8. again, there should be no comma before "but"
9. missing subject and missing indefinite article "an" in the relative clause
10. missing article before Heavy
11. missing article before speed
12. missing article before Heavy again
13. missing article before Scout, twice
14. missing article before health
15. missing article before Heavy, should be capitalized as in previous cases
16. no comma before "all" (disputable)
17. missing reference for "ones" (players comes at the end of the sentence)
18. missing article before "Demoman's"
19. customizations "don't change" and "make" - wrong conjugation
These are only the grammatical errors...
No, you can't object to these unless you were studying English descriptive grammar for four semesters like I have. ;-)
P.S. Yes, I make mistakes as well but at least I'm trying to avoid them... I'm very glad when people point out my errors because only then am I able to learn from them. =)
