Long range limitation

[horselance]

Of course there will not be any limitations. This weapons are particularly effective in mid when more than 1. But that does not mean it is godlike. There are ways to handle them.
Things you should know about long ranges:
-They are much expensive than other ranges. (130% comparing to swarm rocket, 230% comparing to Poison Magic)
-They is no rapid fire long range. ( cooldowns bigger than 1.0 sec always)
-They can't creeps as good as other weapons because of long cooldown and low DPS.
-They hit too far. (Impossible to focus on Enemy Tanks)
-They must fly to hit you better, so they cant stun.
-They must expense their money on weapons, so they cant have hp.

And there are few tricks:
-Don't run from them or they will kill you.
-Use extra creep assault like factories or creep commander.
-Always buy a tank with stun.
-Get a Teleporter ASAP.

These things are acceptable rules always. But -hb is a different matter anyway, there is no money balance in that mode. It is a fun mode only.
I hope these things can help.

EDIT:
Scout + long range is the strongest tactic in -hb. Because it is a creeper tank and dont let you creep as well. But is a FUN mode as mentioned.
