1) Hourglass on Breakthrough Large is the map I found to have extreme frustrating opening experience. With Attacker standing on top of the rooftop of the stadium and rain fire onto the defending side. The first sector basically a free pass with most of the case the defending side just forfeit the first sector to avoid the frustration.
Manifest on Breakthrough Large on the attacker on the other hand, way too far from the actual combat zone
2) Infantry vs Vehicles is just a nightmare on the infantry end. Attack helis fly high above outside the reach of MAA and PAA and rain fire, Scout heli with Hydra rocket is it owned problem, with 3 rockets per kills and high speed, basically if you got caught in the crosshair of a "known how to fly" pilot then you are dead. The abuse of Bolte still going strong, most of my death getting killed by vehicles either come from Bolte or Scout heli, and many locations the terrain caused the glass of the Bolte became bulletproof and cant be shot through unless you are standing on higher elevator, many games turned into farm fest for Bolte campers. Wildcat AA gun is just too weak when fighting air vehicles, limited angle, fast overheat, long cooldown and low damage.Wildcat 40mm is a bit too spammy, 57mm isn't good, fire rate is just too slow and replenish time too slow too. Tank is a bit on the weeker side since it got constant nuked by the C5 drone, the speed acceleration isn't that good.and most tank driver just opted to camp from afar to get some kills instead of getting nuked instanly while trying to provide support for the team.
3) Map needed more LOS blockers or cover:
Hourglass Breakthrough Large, sector A and B
Hourglass Breakthrough 64p, objective A1, basically no cover at all if attacker decided to bulldozered all the houses around A1
Kaleidoscope Breakthrough Large, sector A, between A1 and A2
Breakaway on Breakthrough Large, sector C around oil tankers
Orbital on Breakthrough Large, around Objective A1
4) More transport ground vehicles needed. Quad bike, motocycle, or mini hovercraft available for call-in or deploy straight from the spawn screen.
