So lets talk about Ohmwrecker

TLDR at bottom

This item is pretty much never bought by anyone, and it is never given any attention by boards or Riot. first off, lets compare it to the other armor+health items in just stats 300 health, 50 armor, 150% base health regen, 10% CDR 500 health, 50 armor 500 health, 60 armor, -10% from crit 500 health, armor

So the biggest difference here is that Ohm wrecker exchanges a lot of health for other stats, which may not be a very good trade for a lot of tanks to make if they are going to buy this item, since they can usually just get cdr from , , , or (which will also give better regen). So it already does not look like a good item stat-wise for most tanks.

Now we can look at the passives and actives, which Ohmwrecker appears to have an advantage on. It's defining active is that it can disable turrets, and while this looks like it could be very powerful, I think that it is the reason this item is never bought.

Being able to disable turrets is something that would be very helpful if one was trying to force kills or fights and snowball games. The problem with this is that, in lane especially, tanks are generally less likely to get ahead, and are less likely to try to snowball than other champions, making this active not as usefull to them. This is why I think that Ohmwrecker should be made into a more offensive item so that it can be bought by champions that have a lead and are trying to snowball it more, making that easier to do.

TLDR: Ohm wrecker has stats that are less desireable to tanks than other items could be and it has an active that would be more useful on offensive champions that are trying to snowball leads, so it should be made into an offensive item.

These are my thoughts, tell me what you think and please share yours.
