Not at all, the radius to be affected by omni's ult when he activates it is only 500, this means that your entire team has to be really nearby each other. Which means they're easy target for Black Hole, Reverse Polarity, Vacuum+Wall combo, Warlock's rock, and other crowd control ults.
Not to mention that it doesn't work on buildings until you actually get an Aghanims Scepter which is 4.2k and normally support Omnis can't farm that much, if you're a dps Omni you'd rather focus on something else anyway.
Both his Repel and Guardian Angel can be purged by the small satyr's skill and diffusal blade, meaning Chen, Enchantress, Doom or any hero that normally gets diffusal blade or helm of the dominator will be able to remove his Repel or Guardian Angel by purging it.
There's nothing imba about his repel as all btw, try picking a Naga Siren so that whenever Omni uses repel on someone, you pop your song and the only one that can move around and be attacked would be the guy that's repelled. 5 man gangbang him while the rest of his team is asleep. By the time the song ends it would really screw them up if the one they repelled was their carry or something. A carry cant do a 1v5 fight no matter how farmed he is, considering you guys have a more proper lineup and some teamwork. Also some Naga players do like to get diffusal blade on her because it's honestly not a bad item on her at all.
Stop complaining anything is imba,
there are some heroes that have great skills and work well in a lot of different type of hero composition lineups. Perhaps you should start actually picking them and using them rather than always playing heroes that have mostly single target dps like cancer lancer or Antifun.
wow chill man.
anyway thanks for the tip.
im not a carry. pl and am would not be my type. just had a sudden thought of playing omni as carry cause i love that hero and played it as a support most of the time. wanna explore other ways.
i agree with you on the bolded part. me and my friends play alot of hero combos.
