Ok recent update & comparsion between IS-3 / Defender / Alpine Tiger / IS-3A
Criteria compared based on Tank.GG & actual playing experience (yes I own all of them and play enough games with all of them):
IS-3:- Snapshot/Sidescrape capability:
GREAT (best in Gun + turret turning + hull moving dispersion)
- Brawling/Melee Potential:
Moderate (Lacking armor to brawl effectively, Over-matchable roof if face-to-face)
- Long range fire support:
Below Average (due to shell speed + dispersion + role)
- Medium range fire support:
Moderate (Decent alpha per shot occasional MISS)
- Mobility:
Moderate, Best among the 4, overall terrain resistance + hull traverse very comfortable
- Straight-line rush:
Below Average (limited by top speed)
Conclusion: 1 of the best snapshot tank, but limited by the single-shot gun and top speed. High skill ceiling to unleash the potential but not noob friendly.
Defender:- Snapshot capability:
Below Average (Gun+Turret+hull handling worse than IS-3 by a chunk, only slightly compensate by aim time + frontal armor)
- Brawling/Melee Potential:
GOOD , BEST among the 4 (enemy cannot reliably PEN its frontal armor, almost no frontal weakspots)
- Long range fire support:
BAD (very RNG dispersion)
- Medium range fire support:
BAD (very RNG dispersion)
- Mobility:
Below Average, heavier and slower than IS-3, slightly better on Med/Soft Terrain than IS-3
- Straight-line rush:
BAD (SLOWEST among the 4)
Conclusion: 1 of the most brainless spearhead charging heavy tank, potential limited by the gun itself, reasonably mobile with OP armor of the tier.
Alpine Tiger (Highly recommend go for 100% HEAT shell due to its Silver Bonus modifier better than usual premium tanks)
- Snapshot/Sidescrape capability:
GREAT (as long as avoiding shooting enemy tracks/side skirt spaced armor when using HEAT)
- Brawling/Melee Potential:
GOOD , (HEAT shells with decent reload times, best suited face-to-face slugfest)
- Long range fire support:
BAD (very RNG dispersion, not worth to use expensive HEAT)
- Medium range fire support:
BAD (very RNG dispersion, not worth to use expensive HEAT)
- Mobility:
Below Average,
AVOID Soft Terrain at all COST- Straight-line rush:
Above Average (Fastest among the 4)
Conclusion: Alpine is basically a tier-8 full HEAT shell T-10 heavy tank, with a much weaker engine HP.
IS-3A (highly recommended go for 100% HEAT shell if prefer close range)
- Snapshot capability:
BAD (worst gun/hull moving dispersion among 4)
- Brawling/Melee Potential:
GOOD , (3 shell clipping power + HEAT shell, can even bully tier-9 WZ-111-1-4 at melee range, 0 reload penalty)
- Long range fire support:
BAD (very RNG dispersion, only 1 hits out of 3 shells)
- Medium range fire support:
BAD (very RNG dispersion, only 1 hits out of 3 shells)
- Mobility:
BAD,
FLAT & HARD terrain ONLY- Straight-line rush:
BAD (Worst engine power than IS-3 stock, slow acceleration)
Conclusion: IS-3A is belong the same category of 100% HEAT shell close-range-melee tank, which is AutoReloader version of Alpine Tiger, but much slower especially on Hill/Slopes.
Something to address IS-3A common public misconception about its OP-ness:1. Do not believe 100% of the professional streamer's claims its OP-ness, they are professional + unicrums, most of us are just average players.
2. In current MM with full of "monkeys" + non-skill based MM, IS-3A not really able to always unload the clips without being gang-shotted to death.
3. Its either Long range APCR 1400ms RNG sniping & waste the very little ammo limit, Or Else, go full 100% HEAT shell close quarter battle. There is no place like middle range for IS-3A.
4. Its clipping power only punish careless flankers defensively, and its not happening all the time though.
5. Its still using IS-3 hull paper armor + worst mobility among the 4.
6. Its Inverse Auto-Reloading without any penalty, is in fact, compensating abysmal gun handling and worst mobility, in close-range only.
7. IS-3A still can be killed easily by lower tier tanks, unlike Defender.
8. HEAT shell still have a chance absorbed by tracks/spaced armor caused by its Derpy gun.
